Device Simulation of ZnO/Cu₂O Heterojunction Solar Cells — •Philipp Hering and Bruno. K. Meyer — 1. phys. Inst., Justus-Liebig-Universität, Heinrich-Buff-Ring 16, 35392 Giessen, Germany

Cuprous oxide thin films constitute despite the relatively large band gap (2.17 eV) a very promising absorber material for sustainable low cost photovoltaic application due to the high absorption coefficient and great abundance. A model was developed to describe the illuminated operation of the heterojunction zinc oxide forms with cuprous oxide, taking full account of interface recombination. Numerical analysis was performed, providing insight into the impact of the conduction band discontinuity, interface states and doping on power conversion efficiency
