Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
The basic principles of modern organic solar cells are summarized. Namely, issues on exciton, D/A sensitization, exciton diffusion, blended junction, route formation, \ (\pi - \pi\) stacking orientation, HOMO–LUMO gap tuning, non-radiative recombination, tandem cells, and doping are discussed.
The most significant advances on the development of organic solar cells (OSCs) along the last three decades are presented. Key aspects of OSCs such as the photovoltaic principles regarding the mechanism for the generation of the exciton and the transport of the carriers to the respective electrodes are explained.
Organic materials for photoactive layer Typically, organic solar cells are fabricated using a blend active layer composed by a p-type conjugated polymer used as donor component, and a n-type organic semiconductor as an acceptor component.
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon.
The III-V compound solar cells have contributed as space and concentrator solar cells and are important as sub-cells for multi-junction solar cells.
