About the Book Solar Cell Technology explains how sunlight is converted into electricity and how individual solar cells become modules, arrays and complete photovoltaic systems. The book moves from semiconductor fundamentals to cell structures, manufacturing, characterization, module construction, system design, power electronics, operation, maintenance, safety and emerging technologies. The approach is deliberately practical. Equations are introduced with physical meaning, while engineering sections connect theory with real-world decisions such as orientation, temperature effects, mismatch, shading, wiring, protection and performance monitoring. The book is suitable as a self-study reference, classroom companion or introductory professional guide. It can also serve as a foundation before deeper study of photovoltaic system design, power electronics, semiconductor processing or solar-energy project engineering.
