Novel solar cell with MOS diode for improvement of conversion efficiency

We presented the novel structure of the solar cell that has the metal oxide semiconductor (MOS) diode at the side wall of the electricity generation layer. The purpose of this research is to simulate influence of the field-effect on the recombination of carriers and show the increase of the conversion efficiency of the solar cell. The increase ratios of the conversion efficiency under the gate voltage application are 1.62 and 1.56 times for c-Si and p-Si in comparison with non-gate application equal to the conventional structure, respectively.
