Photovoltaic Characteristics of Low Concentration CdTe Solar Cells

Abstract

It is a reasonable way to increase power generation and reduce the expensive solar cell materials by combining low-cost concentrator and solar cells. The characterization of low concentration CdTe solar cell under standard test condition (STC) and monochromatic light were carried out. The application of concentrator significantly increases the power output of CdTe solar cell. The monochromatic I-V results suggest that the FF of CdTe solar cell was critically affected in the wave length range of 525 to 780 nm. Also the effect of the anti-reflective film on the low concentration CdTe solar cells were revealed, and the results imply that the anti-reflective effect is magnified mainly at the wave length range of 525 to 780 nm.
