Outline of Research at the Start

鉛を含有しない安価で耐久性に優れる環境適応型のハロゲン化ペロブスカイト材料を創製し、これを用いる光電変換素子のエネルギー変換効率を鉛型のレベルまで高めるための材料組成と製膜技術を構築し、無鉛型ペロブスカイトを用いる光電変換素子を高性能化して実用化を促すことを目的とする。ビスマス、スズ、チタン、銀などの金属カチオンで構成されるペロブスカイト結晶の薄膜を高品質で製膜する方法を溶液法と真空蒸着法の両面から検討し、光物性の計測等をもとに光発電における電荷再結合損失を抑制する組成改良と製膜方法の技術基盤を構築し、光電変換素子の高効率化につなげる。

Outline of Final Research Achievements

Thin films of metal halide perovskite with a three-dimensional crystal structure in which lead is replaced with harmless metal cations such as Ag, Bi, Sn, and Ti are formed by solution process and vacuum deposition methods, and their optical properties are evaluated. Photovoltaic deviced using theselead-free perovskite films are fabricated for evaluation of power conversion efficiency (PCE). Among Ag-Bi materials, a PCE of 2.7% was obtained with a thin film of Ag2BiI5, and an efficiency of over 4% was obtained with the double perovskite Cs2AgBiBr6. In addition, as a new development, AgBiS2, which replaced halogen with sulfur, achieved an efficiency of more than 5%. Sn-based perovskites phootovoltaic cells were fabricated using a passivation method to suppress the oxidation of divalent Sn and the best cell achieved a high efficiency of 11.4%.

Academic Significance and Societal Importance of the Research Achievements

この研究成果をもとに、鉛を用いない組成によって環境に無害であり、かつ溶液塗布法を用いて成膜する安価なペロブスカイト光電変換素子が11%以上の高いエネルギー変換効率の性能をもって得られる。これによってペロブスカイト光電変換素子を屋外の太陽光発電に用いる応用から屋内のIoT電源として使う応用まで、社会実装における用途範囲が拡大し、環境上安全で安価な太陽電池が普及することで脱炭素社会への構築に貢献する。
