Abstract

Cuprous oxide (Cu2O) films synthesis by radical oxidation with nitrogen (N2) plasma treatment and different RF power at low temperature (500°C) are studied in this paper. X-ray diffraction measurements show that synthesized Cu2O thin films grow on c-sapphire substrate with preferred (111) orientation. With nitrogen (N2) plasma treatment, the optical bandgap energy is increased from 1.69 to 2.42 eV, when N2 plasma treatment time is increased from 0 min to 40 min. Although the hole density is increased from 1014 to 1015 cm−3 and the resistivity is decreased from 1879 to 780Ωcm after N2 plasma treatment, the performance of Cu2O films is poorer compared to that of Cu2O using RF power of 0. The fabricated ZnO/Cu2O solar cells based on Cu2O films with RF power of 0 W show a good rectifying behavior with a efficiency of 0.02%, an open-circuit voltage of 0.1 V, and a fill factor of 24%.
