The field of photovoltaics (PVs) has seen accelerated growth towards meeting global energy demand. However, the traditional vacuum-based PV cells fabrication approach is expensive, and their performance efficiencies are limited. Thus, there has been tremendous research and development of cost-effective solution-based fabrication of PV cells with improved performance. This has led to new/emerging PV technologies like perovskite solar cells, quantum dot solar cells, organic solar cells, nano-ink based solar cells and dye-sensitized solar cells with impressive efficiencies close to 30 %. As such, these emerging technologies are expected to result in more wide scale application of PV technologies in various forms.

This book comprehensively covers this vastly growing area with reference to fundamental chemical and physical aspects of various solution-processed solar cells including different components of solar cells stacks, their characteristics , and working mechanisms with latest developments as reported in scientific literature. It thoroughly examines these state of the art solution processing approaches covering advances in each technology, highlighting challenges related to cell performance and reliability improvements aimed at a readership of students and researchers in the field. Importantly, the discussions are predicated on the fundamental chemistry and physics concepts of the various types of materials and how their properties are exploited for these technologies.
