Solar energy is available in abundance and is also an extremely clean form of energy found on earth. The need for solar energy evolved and only grew stronger over time due to the over exploitation and rising prices of conventional sources. It is a renewable form of energy which is found freely and can be harnessed using a number of technologies such as solar thermal energy, solar heating, photovoltaic cells, solar architecture and artificial photosynthesis. This book unfolds the innovative aspects in the field of solar energy which will be crucial for the progress of this field in future. It also includes a detailed explanation of the various concepts and applications of this discipline. For all readers who are interested in this area, the case studies included in this book will serve as an excellent guide to develop a comprehensive understanding.
