Thin Film Photovoltaics: Single-Junction and Tandem offers a clear and comprehensive introduction to the fast-growing world of thin film solar cells. It is ideal for scientists, engineers, students, and professionals working in photovoltaics. The book covers both established principles and the latest innovations. Readers will learn about the key factors that affect solar cell performance, device operational principles including internal electric fields, energy band structures, and charge transport. It explores interface engineering, defect passivation, and grain boundary control. Dopant-free transition metal oxides as carrier-selective contacts for silicon heterojunction solar cells is also discussed in detail. Material tuning, bandgap engineering, and wide-bandgap perovskites are highlighted as essential tools for device optimization. The book explains how to scale from lab-scale devices to commercial solar modules.

It covers 2-terminal, 3-terminal, and 4-terminal tandem solar cell architectures. Recombination junctions, strategies to reduce energy losses, and advanced fabrication methods are clearly outlined. Flexible substrates, stress tolerance, and encapsulation techniques are also explored. The use of ultrathin wafers and integration with metal foils is addressed. New materials such as van der Waals chalcogenides and chalco-halides from antimony, bismuth, germanium, and tin are introduced. Their structural and optoelectronic properties are examined along with promising applications in next-generation devices. Thin Film Photovoltaics is a must-have reference for anyone interested in the technologies driving the future of solar energy.
