Abstract

Recently, the flux distribution and Photovoltaic (PV) structure optimization have been paid more attention in the design of concentrating Photovoltaic (CPV) by several researchers while the scale factor is sometimes decided by the processing technology used and cost. However, the same CPV devices with the same concentration ratio under different scales may possess different electrical characteristics. Therefore, this paper presents a comparison of two different scales of compound parabolic concentrating (CPC) PV with the same concentration ratio of 4X, based on the commercial crystalline silicon solar cell. The model is verified by experiment firstly, then the electrical characteristics comparison is performed. The results show that the maximum output power of small-scale CPC-PV cells is 424.960 mW, which is significantly higher than the maximum output power of large-scale CPC-PV cells of 420.713 mW. This means that the small scale one has a better electrical performance than the large scale one in this situation thus, this study will provide a reference for future CPC-PV design.
