With global installed capacity exceeding 2 TW by the end of 2024, photovoltaic solar energy has become one of the leading alternatives for meeting growing electricity demand while reducing environmental impact. Designing efficient and sustainable devices, however, requires a firm grasp of the physics that governs them. This book offers a concise theoretical overview of photovoltaic solar cells, from fundamentals to device architecture. It opens with the expanding PV market, the nature of solar radiation, and standard spectra, then explains photovoltaic conversion through the p-n junction, the single-diode model, and the influence of series and shunt resistances. The key performance parameters derived from the current-voltage characteristic are defined, including short-circuit current, open-circuit voltage, form factor, conversion efficiency, and the Shockley-Queisser limit. The book then surveys four generations of technologies, from crystalline silicon and thin films such as CdTe and CIGS to organic, dye-sensitized, quantum dot, perovskite, kesterite, and tandem cells, comparing their efficiencies, advantages, and limitations. It concludes with the internal structure of the CZTS/Zn(O,S)/ZnO cell, detailing the role of each layer, with particular emphasis on buffer layers and interface band alignment. It thus provides a solid theoretical foundation for anyone working in photovoltaics and thin-film materials.
