The book "Enhancing PbS Solar Cells with Inorganic HTLs" by T. Shrikanth Reddy provides a comprehensive analysis of the latest research and developments in the field of PbS solar cells. PbS is a promising semiconductor absorber material for thin-film photovoltaic devices due to its excellent charge transport and carrier dynamics properties. However, the energy conversion efficiency of PbS solar cells is limited by the inefficient extraction of charge carriers, which can be improved by using inorganic hole transport layers (HTLs). The book explores the use of various metal oxides, sulfides, selenides, and perovskites as inorganic HTLs and their impact on device performance. The author covers various techniques used for the fabrication of PbS solar cells such as doping, annealing, solution processing, vacuum deposition, spin coating, chemical bath deposition, and atomic layer deposition. The book also delves into the importance of interface morphology and surface modification for efficient electron extraction and hole blocking. The book extensively covers the electrical and optical characterization techniques such as X-ray diffraction, scanning electron microscopy, transmission electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, UV-visible spectroscopy, photoluminescence, and external quantum efficiency measurements. The author also emphasizes the stability and lifetime of PbS solar cells and their cost-effectiveness for large-scale production. Overall, this book is a valuable resource for researchers, engineers, and students working in the field of optoelectronics, photovoltaics, and semiconductor materials. It provides an in-depth understanding of the role of inorganic HTLs in enhancing the performance of PbS solar cells, which is crucial for the development of efficient and sustainable solar energy technologies.
