摘要

To investigate substrate orientation effect on the solar cell efficiency, In 0.16 Ga 0.84 As solar cells were grown on GaAs substrates with different miscut angles by metalorganic chemical vapor deposition. It was found that a p-n In 0.16 Ga 0.84 As solar cell grown on a 2°-off GaAs substrate exhibits better conversion efficiency than that grown on a 15°-off GaAs substrate. The poor performance of the 15°-off In 0.16 Ga 0.84 As solar cell could be attributed to the formation of high-density misfit dislocations through strain relaxation, which reduces minority carrier lifetime. The conversion efficiency of a 15°-off In 0.16 Ga 0.84 As solar cell could be improved by using a p-i-n structure. With the employment of the p-i-n structure design, a 15°-off In 0.16 Ga 0.84 As solar cell was demonstrated to show the conversion efficiency close to or even better than that of a 2°-off In 0.16 Ga 0.84 As solar cell with the same structure.
