This highly-regarded textbook provides the readers with the basic principles and advanced concepts of the physics of solar cells, explaining in detail all aspects of solar cell function, the physics behind every single step, as well as the issues to be considered when improving solar cells and their efficiency. It requires no more than standard physics knowledge and enables students and researchers to understand the factors driving conversion efficiency and to apply this knowledge to their own solar cell development. Problems help the student to strengthen its knowledge. The third edition of "Physics of Solar Cells" also introduces the important characterization techniques for solar cells and discussed their respective advantages and disadvantages.
