Dr. P. Jayarama Reddy is an energy consultant to the solar photovoltaic industry and serves as a board member of several international renewable energy companies related to solar module fabrication, power generation from biomass and municipal solid waste. He is a retired professor of Physics (Sri Venkateswara University, Tirupathi, India) and has worked in various big research laboratories at Cornell University (US), Imperial College London (UK), Charles University (Czech Republic), and Stuttgart University (Germany). Dr. Reddy is a Fellow of the Institute of Physics (UK) and has published a number of papers on polycrystalline thin fi lm solar materials and cells, as well as the book Science and Technology of Photovoltaics, published by BS Publications / CRC Press/Balkema.

Professor Jayarama Reddy is one of the best known, accomplished and inspiring scientists and teachers of PV in India. This exciting book includes the wisdom and knowledge of a master scientist and teacher who has devoted his life to developing PV for use not just in India but throughout the world. Both young scientists, new to the field, and experienced scientists will find its insights useful and inspiring as we move forward to provide the world with the energy it needs. R. W.
