ABSTRACT

This chapter presents an overall review of progress in organic photovoltaics devices (OPVs). Individual sections trace the development of molecular, polymer, and inorganic–organic hybrid OPVs from the earliest devices to the current state of the art. Within each class of device, a different approach has been taken with multilayer cells having the best performance for molecular OPVs and blends of polymers and fullerene derivatives having the best performance of polymer OPVs. The chapter concludes with a discussion of solid-state dye-sensitized solar cells and a comparison of OPV performance to inorganic solar cells.
