上转换太阳电池的数值模拟
Numerical Simulation of Up-Conversion Solar Cells
摘要
Abstract
The theoretical efficiency limit of the solar cells for nonconcentrated sunlight was calculated using detailed balance model. It is showed that the maximum conversion efficiency of 31% is obtained for single-junction solar cell under a 6000 K blackbody spectrum. When up-converter is applied, the upper limit of energy conversion efficiency is 47. 3% for single-junction solar cell. For double-junction solar cells, when the band gap of top cell is fixed at 1.7 eV and the band gap of bottom cell is varied from 1. 1 eV to 1. 5 eV, maximum efficiency is found to be 39. 9%. When the up-converter is used, the efficiency is 47.4%.关键词
