TLDR
The first solution-processed depleted bulk heterojunction colloidal quantum dot solar cells are presented, which allows high absorption with full depletion, thereby breaking the photon absorption/carrier extraction compromise inherent in planar devices.Abstract:
The first solution-processed depleted bulk heterojunction colloidal quantum dot solar cells are presented. The architecture allows high absorption with full depletion, thereby breaking the photon absorption/carrier extraction compromise inherent in planar devices. A record power conversion of 5.5% under simulated AM 1.5 illumination conditions is reported.read more
