Abstract

Indoor and outdoor power generation characteristics of InGaP // Si spectrum splitting solar cells were measured. In indoor measurement using solar simulator, a conversion efficiency of 28.6% and 30% was achieved at 1 sun and 5.7 suns, respectively. For outdoor measurements, on sunny days, the average efficiency per day is 25%. When the loss of the solar irradiance caused by the measurement box is corrected, the conversion efficiency is 30%. Daily total output is roughly proportional to the accumulated solar irradiance on a daily basis, and the average efficiency of 27% was demonstrated.
