Photovoltaic (PV) technologies have a substantial role in meeting electric; power needs in the next century, especially with an expected competitive; position compared to conventional power-generation and other renewable-; energy technologies. Thin-film photovoltaic modules based on CdTe,; CuInSe2 or Si can potentially be produced by economical, high-volume; manufacturing techniques, dramaticallyreducing component cost.; However, the translation of laboratory thin-film technologies to first-time,; large-scale manufacturing has been much more difficult than expected.; This is due to the complexity of the processes involved for making large-; area PV modules at high rates and with high yields, and compounded by; the lack of a fundamental scientific and engineering base required to;properly engineer and operate manufacturing equipment. In this paper, we; discuss the need to develop diagnostics tools and associated predictive; models that quantitatively assess processing conditions and product; properties. Incorporation of the diagnostic sensors into both laboratory; reactors and manufacturing facilities will (1) underpin the development of; solar cells with improvedefficiency, and (2) accelerate the scale-up; process through intelligent process-control schemes. 'Next-generation'; high-performance (e.g., >25% conversion efficiency) thin-film PV; modules will also be assessed, along with critical issues associated with; their development.

"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.

The sun has bathed our planet in its radiant energy for millennia, a silent and abundant source of power. Yet, for much of human history, harnessing this power seemed like a dream.

Thin film photovoltaic-based solar modules produce power at a low cost per watt. They are ideal candidates for large-scale solar farms as well as building-integrated photovoltaic applications. They can generate consistent power, not only at elevated temperatures but also on cloudy, overcast days and at low sun angles.Thin film photovoltaics are second-generation solar cells produced by depositing one or more thin layers, or thin films, of photosensitive material on a suitable substrate such as glass, polymer, or metal. Thin film solar cells are based on various materials such as cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin film silicon (a-Si, TF-Si) are commercially used in several conventional and advanced technologies.

The first comprehensive book on thin-film solar cells, potentially a key technology for solving the energy production problem in the 21st century in an environmentally friendly way. It covers a wide range of scientific and technological aspects of thin film semiconductors - deposition technologies, growth mechanisms and the basic properties of amorphous and nano-crystalline silicon - as well as the optimum design theory and device physics of high-efficiency solar cells, especially of single-junction and multi-junction solar cells. The development of large-area solar cell modules using single and multi-junction solar cells is also considered. Examples of recent photovoltaic systems are presented and analysed.

With the decline in the world's natural resources, the need for new and cheaper energy sources is evolving. One such source is the sun which generates heat and light which can be harnessed and used to our advantage. This reference book introduces the topic of photovoltaics in the form of flexible solar cells. There are explanations of the principles behind this technology, the engineering required to produce these products and the future possibilities offered by this technology. The chemistry and physics of the cells (both organic and inorganic) are clarified as well as production methods, with information how this can then be applied to the nanoscale as well. A complete guide to this new and exciting way of producing energy which will be invaluable to a variety of people from material scientists, chemists, electrical engineers, to management consultants and politicians.

Going from the inner city to the open desert, a seasoned environmental advocate looks at solar energy’s remarkable ascent and its promise for America’s future Solar power was once the domain of futurists and environmentally minded suburbanites. Today it is part of mainstream America. Scan the skyline of downtown neighborhoods, check out the rooftop of the nearest Walmart, and take a close look at your local sports arena. Chances are you’ll find solar panels in those and many other unexpected places. In Harness the Sun, Philip Warburg takes readers on a far-flung journey that explores America’s solar revolution. Beginning with his solar-powered home in New England, he introduces readers to the pioneers who are spearheading our move toward a clean energy economy. We meet the CEOs who are propelling solar power to prominence and the intrepid construction workers who scale our rooftops installing panels. We encounter the engineers who are building giant utility-scale projects in prime solar states like Nevada, Arizona, and California, and the biologists who make sure wildlife is protected at those sites. Warburg shows how solar energy has won surprising support across the political spectrum. Prominent conservatives embrace solar power as an emblem of market freedom, while environmental advocates see it as a way to reduce America’s greenhouse gas emissions. At the same time, economic-justice activists celebrate solar’s potential to lift up low-income communities, and Native American leaders welcome the income and jobs that the industry will bring to their communities. Yet solar energy has its downsides and detractors too. Conservationists worry about the impact of large solar farms on protected animal species, and some local citizens groups resent the encroachment of solar projects on farmland and open spaces. Warburg gives voice to those at the epicenter of these conflicts and points the way to constructive solutions. Harness the Sun offers a grounded, persuasive vision of America’s energy future. It is a future fueled by clean, renewable sources of power, with solar at center stage.
