- Abstract
High‐efficiency, vacuum‐deposited small‐molecule organic tandem and triple‐junction photovoltaic cells are demonstrated. The devices are composed of two sub‐cells with minimal absorption spectral overlap. A nearly transparent fullerene/wide‐energy gap organic mixture is introduced as the interconnecting blocking layer to further reduce cell losses. A power conversion efficiency of 10.0% is achieved for the tandem cell and 11.1% is achieved for a triple‐junction cell.
