| Abstract(in English) | We have investigated InGaN/GaN MQW solar cells on the relationship between short circuit current and the MQW structure. We reported that higher short circuit current was obtained in solar cells with thinner GaN barrier layer and with more numbers of InGaN/GaN period. This tendency can be explained by the hypothesis that the transportation of photo-induced carriers is determined by the diffusion process with some diffusion length. Based on this model, we find that the MQW structure with thinner barrier layer are advantageous for higher short circuit current. |
