In this research, photoanodes on the basis of a CdS/CdSe multilayer film, where CdSe-doped with Cu were successfully fabricated and optimized at a 3% doping concentration. The highest performance of quantum dot solar cells is 4.24%. This result is also confirmed by studying the optical and electrica...
