Abstract (in Japanese) (See Japanese page) 
(in English) We have investigated InGaN/GaN multiple quantum well (MQW) solar cells in terms of the relationship between the short-circuit current and the MQW structure. We previously reported that the short-circuit current dependence on the number of well can be well explained by the hypothesis that the transport characteristics of photoinduced carriers are characterized by the “specific length” within which carriers photoinduced in the InGaN well layer can move before recombination. In this report, we estimated the specific length of several MQW structures and the specific length depends on the thickness of well layer more strongly than on that of barrier layer. We also investigate the relationship between the specific length and the MQW structure. The optimum MQW structure for yielding higher short-circuit current can be determined using the specific length and the absorption process in the MQW structure.
