Copper Oxide (Cu2O) Sputtering Target

Cuprous oxide (Cu2O) exhibits great potential as an absorber layer in solar cell systems due to its remarkable optical and 

electrical properties, its abundant availability, and its cost low cost. Recent developments in Cu2O thin films have 

focused on their improved optical and electrical properties, particularly in optoelectronic applications such as solar cells, 

light-emitting diodes, and photodetectors, demonstrating their potential to advance renewable energy technologies and 

electronic devices. Copper oxide (CuO) and cuprous oxide (Cu2O) are two important phases with distinct band gaps. 

The p-type semiconductor Cu2O, which has a straight bandgap between 2.0 and 2.4 eV, is well suited for its function 

as an absorber layer in solar energy cells, while CuO, with a band gap between 1.9 eV and 2.1 eV, is more suitable 

for energy harvesting and sensing.
