Abstract

Heterostructure comprising two different materials offer an extra degree of freedom to control absorption band and energy level for more efficient optoelectronic devices. Nevertheless, building the efficient charge transport platform is challenging because of the different physical and chemical nature of those. Colloidal quantum dots (CQDs) and polymer hybrid structures have steadily been studied as well, however, the rational strategy to efficiently extract charge have not been proposed so far; only exhibiting a power conversion efficiency (PCE) of 6 ~ 7 %. Here, we propose a new hybrid architecture that synergistically exploits the benefits of CQDs and organics in photovoltaics by introducing small molecules into a CQD/organic stacked structure. The small molecular bridge, mixed in polymer regime facilitates exciton dissociation and charge transfer to the CQDs layer, leading the high PCE of 13.1%.
