Synergistic photocurrent addition in hybrid quantum dot: Bulk heterojunction solar cells

The effect of a thin PbS quantum dot (QD) layer on the performance of hybrid quantum-dot-organic solar cells (QD-OSCs) was investigated. The PbS QD layer is able to function as a photosensitizing layer with PTB7/PC71BM bulk heterojunction to improve short circuit current density from 15.4 mA cm−2 to 17.0 mA cm−2 and power conversion efficiency from 7.56% to 8.30%. 224
