Abstract

The influence of semiconductor layer morphology on the performance of solution-processed ZnO/Cu₂O photovoltaics has been examined. ZnO films were prepared using three highly scalable, cost-effective methods: electrodeposition, zinc acetate decomposition, and diethyl zinc decomposition. To optimize device performance, it is found that a low density of nano-scale pores in the ZnO layer and large grains in the Cu₂O is necessary. Through optimizing the ZnO morphology, one of the highest fill factors observed to date (up to 54%) in solution-processed ZnO/Cu₂O was achieved. This value is comparable with the fill factor of the record-efficiency ZnO/Cu ₂O device, which was prepared with much larger energy inputs.
