Origins of Non-Ideal CurrentVoltage Characteristics of Si Solar Cells

Más información sobre el libro

Focusing on the impact of defects in multicrystalline silicon solar cells, this book delves into how these imperfections affect power conversion efficiency, particularly in current-voltage characteristics. It examines various defects and their mechanisms, emphasizing breakdown behavior and reverse current. The use of spatially resolved lock-in thermography for analyzing breakdown sites is highlighted, along with detailed descriptions of early, defect-induced, and avalanche breakdown types. This resource is tailored for scientists and engineers in solar cell research and development.
