Advance in Cu20-ZnO Solar cells and investigation of Cu20-ZnO heterojunction fabricated by magnetron sputtering
Cuprous oxide (Cu20),with a direct band gap of 2.17eV,is a natural p-type semiconductor owning a high absorption coefficient in the visible light region.Zinc oxide (ZnO),an intrinsic n-type semiconductor with a direct band gap of 3.37eV,is considered to be a promising partner with Cu20 for p-n heterojunetion.Cu20-ZnO heterojunetion have shown great potential for photovoltaic application due to the low-cost,nontoxicity,abundance and variety of preparation methods.In this article,a detailed survey on the previous work carried on Ct20-ZnO heterojunetion solar cells in recent years has been presented.The fabrication methods and structures of the heterojunction solar cells are discussed and an analysis of the existing problems is given.Possible areas for future research m the field are outlined and some suggestions were made based on our investigation of the Cu20-ZnO heterojunctions fabricated by magnetron sputtering.
