Device model for the operation of polymer/fullerene bulk heterojunction solar cells
TL;DR: In this paper, a numerical device model that consistently describes the currentvoltage characteristics of polymer:fullerene bulk heterojunction solar cells is developed, and the model predicts that an increased hole mobility together with a reduction of the acceptor strength of 0.5 eV will lead to a maximum attainable efficiency of 5.5% in the PPV/PCBM-based solar cells.
