Abstract:
1. A solar cell comprising: an electron conductor layer comprising titanium dioxide; a quantum dot layer comprising quantum dots; a hole conductor layer comprising at least one of poly(3-hexylthiophene), poly[2,5-dimethoxy-1,4-phenylene-1,2-ethenylene,2-methoxy-5-2-ethylhexyloxy-1,4-phenylene-1,2-ethylene), poly(9,9-dioctylfluorene-co-N-(4-(3-methylpropyl)-diphenylamine), or 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′spirobifluorene; an electron inhibiting/hole transporting layer disposed between the quantum dot layer and the hole conductor layer, wherein the electron inhibiting/hole transporting layer comprises ZnS, poly(N-vinylcarbazole), poly(9,9-dioctylfluorenyl-2,7-diyl), or poly(N,N′-bis(4-butylphenyl)-N,N′-bis(phenyl)benzidine); and an absorber layer disposed between the electron conductor layer and hole conductor layer, the absorber layer comprising a photosensitive dye.
