However, their open-circuit voltages (VOC) are not uniformly distributed within a wafer due to the preferential glide plane of β dislocations. Furthermore, the effect of dislocations on the carrier recombination process is still under discussion. We investigated two types of InGaAs solar cells with the InGaP step-graded buffer layers grown on the vicinal GaAs substrate. The first cell showed a high VOC (HighV), and the preferential glide plane of β dislocations was well controlled using the vicinal substrate. The second cell had a low VOC (LowV), where the preferential glide planes of β dislocations were nonuniformly distributed within the cell due to the InGaP ordering effect. In this study, laser heterodyne photothermal displacement mappings, microwave photoconductivity decay mappings, and photoluminescence measurements were performed to discuss carrier recombination properties. In the HighV cell, almost uniform signal distributions were observed. On the other hand, the observed signals in the LowV cell were nonuniformly distributed. We also found that the obtained results of nonuniformity correspond to the distribution of preferential glide planes of β dislocations. These results indicate that the VOC reduction strongly depends on the direction of the preferential glide plane of β dislocations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34481/0002000816","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty
