In light of limited energy reserves and increasing environmental issues, the potential use of photovoltaic solar cells is becoming increasingly important. This unique foundational textbook provides a comprehensive and highly illustrative introduction to the semiconductor physics underlying photovoltaics and their modern applications. "Photovoltaics: Fundamentals and Applications" offers a thorough introduction to the semiconductor physics of photovoltaics and describes their applications, including the latest approaches. The price, lifespan, and efficiency of solar cells will determine whether photovoltaics will make a significant contribution to energy supply in the future. This comprehensive and up-to-date work addresses these topics.
