Fabrication and optimization of N-Cu2O thin film using electrodeposition method for homojunction solar cell

Cuprous oxide (Cu2O) is a promising semiconductor that has been getting attention as the alternative material for solar cell application. It is abundant, low cost and non-toxic to the environment. A homojunction Cu2O is said to provide high conversion efficiency for solar cell. However, as Cu2O is a...
