From last few decads world is looking for the substituents of conventional sources of energy. The science community is looking for sustainable, reliable and economic sources of alternate energy. The present book is giving a method of convert and storage of solar energy. There are number of ways to convert the solar energy into less diffuse, utilisable and useful form. The author has selected the photogalvanic conversion path. After a prolonged research work in the field, the author is explaining the facts, myths and methods to harness this energy. The present book is based on the method which exposed the electrodes in two different conditions one in which cell placed in dark condition and second solar light exposed condition. The book is the tool for the fellows who want to harness the solar energy by the photochemical process.
