Cuprous oxide (Cu2O) is a p-type semiconductor with direct band-gap energy of 2.0 eV, which has been regarded as one of the most promising materials for application in photovoltaic cells. In addition, it is known that Cu2O has abundantly available on the earth and exhibit numerous advantages, such as non-toxicity, high absorption coefficient in visible regions and low cost producibility. In this paper, Cu2O thin films were deposited by radio-frequency (rf) magnetron sputtering at different substrate temperatures. The Cu2O thin films are characterized using XRD, SEM and UV-visible spectroscopy to study the effect of substrate temperature on the structural and optical properties of films. |
