Summary : The fundamental concept of the book is to explain how to make thin film solar cells from the abundant solar energy materials by low cost. The proper and optimized growth conditions are very essential while sandwiching thin films to make solar cell otherwise secondary phases play a role to undermine the working function of solar cells. The book illustrates growth and characterization of Cu2ZnSn(S1-xSex)4 thin film absorbers and their solar cells. The fabrication process of absorber layers by either vacuum or non-vacuum process is readily elaborated in the book, which helps for further development of cells. The characterization analyses such as XPS, XRD, SEM, AFM etc., lead to tailor the physical properties of the absorber layers to fit well for the solar cells. The role of secondary phases such as ZnS, Cu2-xS,SnS etc., which are determined by XPS, XRD or Raman, in the absorber layers is promptly discussed. The optical spectroscopy analysis, which finds band gap, optical constants of the films, is mentioned in the book. The electrical properties of the absorbers deal the influence of substrates, growth temperature, impurities, secondary phases etc. The low temperature I-V and C-V measurements of Cu2ZnSn(S1-xSex)4 thin film solar cells are clearly described. The solar cell parameters such as efficiency, fill factor, series resistance, parallel resistance provide handful information to understand the mechanism of physics of thin film solar cells in the book. The band structure, which supports to adjust interface states at the p-n junction of the solar cells is given. On the other hand the role of window layers with the solar cells is discussed. The simulation of theoretical efficiency of Cu2ZnSn(S1-xSex)4 thin film solar cells explains how much efficiency can be experimentally extracted from the cells. One of the first books exploring how to conduct research on thin film solar cells, including reducing costs Detailed instructions on conducting research

Summary : Beginning with an overview and historical background of Copper Zinc Tin Sulphide (CZTS) technology, subsequent chapters cover properties of CZTS thin films, different preparation methods of CZTS thin films, a comparative study of CZTS and CIGS solar cell, computational approach, and future applications of CZTS thin film solar modules to both ground–mount and rooftop installation. The semiconducting compound (CZTS) is made up earth–abundant, low–cost and non–toxic elements, which make it an ideal candidate to replace Cu(In,Ga)Se2 (CIGS) and CdTe solar cells which face material scarcity and toxicity issues. The device performance of CZTS–based thin film solar cells has been steadily improving over the past 20 years, and they have now reached near commercial efficiency levels (10%). These achievements prove that CZTS–based solar cells have the potential to be used for large–scale deployment of photovoltaics. With contributions from leading researchers from academia and industry, many of these authors have contributed to the improvement of its efficiency, and have rich experience in preparing a variety of semiconducting thin films for solar cells.

Summary : Photovoltaic systems enable the sun’s energy to be converted directly into electricity using semiconductor solar cells. The ultimate goal of photovoltaic research and development is to reduce the cost of solar power to reach or even become lower than the cost of electricity generated from fossil and nuclear fuels. The power conversion efficiency and the cost per unit area of the phototvoltaic system are critical factors that determine the cost of photovoltaic electricity. Until recently, the power conversion efficiency of single-junction photovoltaic cells has been limited to approximately 33% - the so-called Shockley-Queisser limit. This book presents the latest developments in photovoltaics which seek to either reach or surpass the Shockley-Queisser limit, and to lower the cell cost per unit area. Progress toward this ultimate goal is presented for the three generations of photovoltaic cells: the 1st generation based on crystalline silicon semiconductors; the 2nd generation based on thin film silicon, compound semiconductors, amorphous silicon, and various mesoscopic structures; and the 3rd generation based on the unique properties of nanoscale materials, new inorganic and organic photoconversion materials, highly efficient multi-junction cells with low cost solar concentration, and novel photovoltaic processes. The extent to which photovoltaic materials and processes can meet the expectations of efficient and cost effective solar energy conversion to electricity is discussed. Written by an international team of expert contributors, and with researchers in academia, national research laboratories, and industry in mind, this book is a comprehensive guide to recent progress in photovoltaics and essential for any library or laboratory in the field.

Summary : The low cost and low temperature electrochemical deposition technique was employed to grow Cu2O thin films and ZnO:Al thin films were deposited by d.c. magnetron sputtering in order to fabricate solar cells. The potentiostatic and galvanostatic electrodeposition modes were used to deposit the Cu2O thin films. Raman spectra of thin films have shown characteristic frequencies of crystalline Cu2O. The contact between Cu2O and Au is found to be an Ohmic contact. The devices grown by a potentiostatic mode have higher efficiency than those grown by a galvanostatic mode. The optimum thickness of Cu2O thin films as an absorber layer in solar cells. was found to be around 3 µm respect to a high efficiency. Flexible and light weight solar cell was fabricated on plastic substrate.

Summary : "The development of sustainable energy sources with a high energy return on energy investment (EROI) that can substitute fossil fuels is a must in order to avoid the collapse of our current civilization. In this context, this work explores the feasibility of fabricating efficient Cu2ZnSn(Sx,Se1-x)4 (kesterite) solar cells on three strategic substrates: polyimide, ceramic and SnO2:F-coated soda-lime glass (SLG/FTO). These substrates present several advantages with respect to the standard SLG/Mo. Polyimide is compatible with roll-to-toll production processes and easily integrable in many applications thanks to its light weight and flexibility, ceramics have a direct application in building-integrated photovoltaics as solar tiles and the transparency of SLG/FTO enables advanced photovoltaic concepts like bifacial and tandem solar cells as well as the fabrication of semi-transparent devices. Their combination with a sustainable thin film photovoltaic technology based on Earth-abundant materials like kesterites has the potential of decreasing the energy fabrication cost and, thus, of increasing the EROI of photovoltaics through: 1) high throughput production, 2) integration and 3) advanced applications and functionality. However, these substrates also present several drawbacks. Alkalis, especially Na, are fundamental to achieve high efficiency devices but polyimide and ceramics are alkali-free materials. Likewise, FTO acts as a barrier for alkalis. In addition, polyimide presents a low thermal robustness that limits process temperatures below 500oC, ceramics are very rough and possess detrimental impurities and the use of FTO as back contact leads to a non-optimum p-kesterite/n-FTO interface. This work focuses on the implementation of specific strategies to adapt the kesterite solar cell fabrication process to the characteristics of the different substrates. A combination of alkaline doping and low-temperature annealings is studied for the fabrication of Cu2ZnSnSe4 solar cells on polyimide. While doping with NaF and KF is found to lead to critical improvements, working at low temperature is linked to the formation of SnSe2. This phase decreases the open-circuit voltage of the devices and is the main factor controlling their performance. Further experimentation leads to a 4.9% efficiency record device by combining NaF and Ge doping and a 480oC annealing. In the case of ceramic, vitreous enamels with controlled amounts of Na2O in their composition are used as surface smoothers, Na sources and impurity barriers, simultaneously. However, large amounts of Na2O in the enamel composition result in high densities of surface defects: undulations, pinholes and cracks. While undulations and pinholes are rather benign, cracks strongly deteriorate the back contact. In addition, the annealing time needs to be controlled to avoid the formation of SnSe2. Besides these issues, enamelled ceramic substrates are observed to behave similarly to SLG yielding a record Cu2ZnSnSe4 device with a 7.5% efficiency. Regarding SLG/FTO, the addition of transition metal oxides (TMOs) and/or Mo:Na nanolayers is studied as an approach to improve the back interface of the devices. Mo:Na is found to alleviate shunting and recombination issues and to protect FTO from degradation during annealing which leads to highly improved devices, especially for Cu2ZnSnS4. On the other hand, TMOs introduce a severe current blockage. However, the combination of the TiO2 and V2O5 with Mo:Na is observed to boost the beneficial effects of the latter in Cu2ZnSnSe4 and Cu2ZnSn(S,Se)4 devices. Although these multi-layered back interfaces exhibit a complex behaviour, this approach results in record efficiencies of 6.2%, 6.1% and 7.9% for Cu2ZnSnSe4, Cu2ZnSnS4 and Cu2ZnSn(S,Se)4 devices, respectively. These results represent the highest efficiencies ever reported for kesterite solar cells fabricated on polyimide, ceramic and transparent substrates and give proof of their large potential for sustainable kesterite-based photovoltaics." -- TDX.

Summary : This book examines the electronic structure of earth-abundant and environmentally friendly materials for use as absorber layers within photovoltaic cells. The corroboration between high-quality photoemission measurements and density of states calculations yields valuable insights into why these materials have demonstrated poor device efficiencies in the vast literature cited. The book shows how the materials’ underlying electronic structures affect their properties, and how the band positions make them unsuitable for use with established solar cell technologies. After explaining these poor efficiencies, the book offers alternative window layer materials to improve the use of these absorbers. The power of photoemission and interpretation of the data in terms of factors generally overlooked in the literature, such as the materials’ oxidation and phase impurity, is demonstrated. Representing a unique reference guide, the book will be of considerable interest and value to members of the photoemission community engaged in solar cell research, and to a wider materials science audience as well.

Summary : "You, 0 Sun, are the eye of the world You are the soul of all embodied beings You are the source of all creatures You are the discipline of all engaged in work" - Translated from Mahabharata 3rd Century BC Today, energy is the lifeline and status symbol of "civilized" societies. All nations have therefore embarked upon Research and Development pro grams of varying magnitudes to explore and effectively utilize renewable sources of energy. Albeit a low-grade energy with large temporal and spatial variations, solar energy is abundant, cheap, clean, and renewable, and thus presents a very attractive alternative source. The direct conver sion of solar energy to electricity (photovoltaic effect) via devices called solar cells has already become an established frontier area of science and technology. Born out of necessity for remote area applications, the first commercially manufactured solar cells - single-crystal silicon and thin film CdS/Cu2S - were available well over 20 years ago. Indeed, all space vehicles today are powered by silicon solar cells. But large-scale terrestrial applications of solar cells still await major breakthroughs in terms of discovering new and radical concepts in solar cell device structures, utilizing relatively more abundant, cheap, and even exotic materials, and inventing simpler and less energy intensive fabrication processes. No doubt, this extraordinary challenge in R/D has led to a virtual explosion of activities in the field of photovoltaics in the last several years.

Summary : Nanostructured solar cells are very important in renewable energy sector as well as in environmental aspects, because it is environment friendly. The nano-grating structures (such as triangular or conical shaped) have a gradual change in refractive index which acts as a multilayer antireflective coating that is leading to reduced light reflection losses over broadband ranges of wavelength and angle of incidence. There are different types of losses in solar cells that always reduce the conversion efficiency, but the light reflection loss is the most important factor that decreases the conversion efficiency of solar cells significantly. The antireflective coating is an optical coating which is applied to the surface of lenses or any optical devices to reduce the light reflection losses. This coating assists for the light trapping capturing capacity or improves the efficiency of optical devices, such as lenses or solar cells. Hence, the multilayer antireflective coatings can reduce the light reflection losses and increases the conversion efficiency of nanostructured solar cells.
