TLDR
In this paper, solid state hybrid solar cells with hybrid organolead halide perovskites (CH3NH3PbBr3 and CH3NH 3PbI3) as light harvesters and p-type polymer poly[N-9-hepta-decanyl-2,7-carbazole-alt-3,6-bis(thiophen-5-yl)-2,5-dioctyl-2.5-di-hydropyrrolo[3,4]-pyrrole-1Abstract:
Solid state hybrid solar cells with hybrid organolead halide perovskites (CH3NH3PbBr3 and CH3NH3PbI3) as light harvesters and p-type polymer poly[N-9-hepta-decanyl-2,7-carbazole-alt-3,6-bis(thiophen-5-yl)-2,5-dioctyl-2,5-di-hydropyrrolo[3,4-]pyrrole-1,4-dione] (PCBTDPP) as a hole transporting material were studied. The CH3NH3PbBr3-sensitized hybrid devices display an outstanding open circuit voltage (Voc) of ∼1.15 V, and the CH3NH3PbI3-based cells exhibit a power conversion efficiency (PCE) of ∼5.55% along with high stability. The present results show that PCBTDPP is superior to the model p-type polymer P3HT as a HTM in these hybrid solar cells to achieve remarkably high Voc and high PCE. The possible mechanisms have been suggested.read more
