A review of the principles of operation of organic solar cells

This review presents the working principles of organic solar cells (OSCs). This class of photovoltaic devices has been extensively studied and optimized for future commercialization due to its optoelectronic characteristics, currently obtaining energy conversion efficiency, in the laboratory, comparable to commercial inorganic solar cells. This work presents the characteristics of organic solar cells compared to other generations of photovoltaic devices as well as detailing the operating principles of OSCs, with an emphasis on the generation of free charges from conjugated polymers.
