摘要: Abstract The influence of semiconductor layer morphology on the performance 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 decomposition. To optimize device performance, it is found that a low density nano-scale pores in large grains Cu2O necessary. Through optimizing morphology, one highest fill factors observed to date (up 54%) was achieved. This value comparable with factor record-efficiency device, which much larger energy inputs.
