Spatially Resolved Characterization in Thin-Film Photovoltaics

More about the book

This book focuses on the spatial characterization of solar cells and PV modules, serving as both a monograph and a concise guide to advanced characterization techniques. It covers various approaches, including visual imaging, electro- and photo-luminescence imaging, thermography, and light beam induced mapping. Special attention is given to luminescence image acquisition and interpretation due to its significant potential. The characterization techniques are paired with simulation tools, making the content accessible to students, senior researchers in R&D, and industry engineers who are new to spatial characterization in solar technology. The material is grounded in real-world case studies of thin-film PV devices. Key features include a review of spatially resolved characterization techniques and SPICE simulations in photovoltaics, as well as the application of these techniques to identify inhomogeneities in small area CdTe and dye-sensitized solar cells. Additionally, it presents case studies of electroluminescence imaging for various commercial PV modules, including c-Si, CIGS, CdTe, a-Si, and tandem and triple junction thin-film-Si. This comprehensive resource aims to enhance understanding and application of spatial characterization in the field.
