"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.
"My husband was an erudite gentleman; an avid reader from childhood, his breadth of knowledge was extensive. He was also charming, vivacious and mischievously funny; all of which attributes, in addition to his love of literature, history and science, surfaced in his Weather Eye column over the years. Here, I have tried to select articles that demonstrate these aspects of his character so that the reader may delight in him afresh." From the Introduction by Anne McWilliams Brendan McWilliams column, Weather Eye, that was published daily for almost 2 decades in The Irish Times, was one of the most successful and best-loved features in modern Irish journalism. The book comprises Anne Allegation Program Annual Trends Report- Calendar Year 2010 free epub McWilliams' favourite pieces from Brendan's work which has not previously appeared in book form. Sometimes historical, sometimes scientific, sometimes literary, sometimes humorous - all the articles are informative, entertaining and display the authors great passion for imparting knowledge.
