Analysing the Sputtered Al Doped ZnO on <111>-Oriented Cu2O Heterojunction Solar Cell with Improved Performance

 

Cu2O/AZO photovoltaic (PV) devices that are electrodeposited are promising low-cost solar cells. During the sputtering process, both layers of Cu2O and AZO heterojunction topologies are investigated as a function of AZO target-Cu2O substrate distance. The Cu2O/AZO PV device was made by electrodepositing a 111>-p-Cu2O layer on an Au (111)/Si wafer substrate and then sputtering the AZO layer on top. Under AM1.5 illumination, the Cu2O/AZO PV device demonstrated photovoltaic performance, which varied depending on the target-substrate distance. The damage at the Cu2O/AZO interface was reduced by increasing the target-substrate distance when sputtering the AZO layer. As a result, the Voc and power conversion efficiency were improved from 0.16 V and 0.46 percent to 0.30 V and 0.64 percent, respectively.
