Abstract
In this chapter, the proposals for future organic solar cells are discussed: the exciton dissociation using single bipolar band-conductive organic semiconductors, doped organic single-crystal substrates with a long exciton diffusion length, and lateral cells showing the efficiency beyond SQ-limit. A critical advantage of organic semiconductors is their suitability for a fine division of the solar spectrum. Suppression of non-radiative recombination dissipated to molecular vibration and trap-assisted non-radiative recombination is a cutting-edge issue for organic solar cells. Voc-loss due to non-radiative recombination would be suppressed to an extent close to the SQ-limit. The spatial and energetic nature of carrier traps should be clarified to suppress the trap-induced recombination. The research on organic solar cells has advanced gradually, on par with that of inorganic solar cells.
