Outline of Final Research Achievements |
We investigated the solution-processed n-type crystalline Si(n-Si)/perovskite FACsPbI3 tandem solar cells. For the bottom n-Si/PEDOT:PSS heterojunction solar cells, we studied the solution-processed TiO2 as AR coating layer and hole-blocking layer at the cathode interface. The power conversion efficiency (PCE) increased to 15.4% by adjuting the layer thickness of TiO2. For the bottom perobskite FA0.8Cs0.2PbI3 thin-film solar cells, the PCE of 16-20% has been establihed by using TSC/DMF/CHP cosolvent using SnO2 as an electron transporting layer. We extend to the fabrication of 2-terminal monolicic tandem solar cell of n-Si/Perovksite using Ag nanowire adn obtained 14.% with a open-circuit voltage of 1.57V

Academic Significance and Societal Importance of the Research Achievements |
塗布プロセスによる結晶Si系太陽電池を下部素子、FAPbIBrペロブスカイト薄膜太陽電池を上部素子とした2接合太陽電池の開発を実施した。ペロブスカイト薄膜太陽電池の高効率化ではI/Br組成比によるバンドギャップ制御と酸化スズを電子輸送層とした太陽電池の高効率化を検討した。その結果I/Br組成比の調整により効率15-16%を得た。またPEDOT:PSS/SnO2接合をPEDOT:PSS成膜時の溶媒EG添加量の調整によりオーミックから整流特性まで制御できることを明らかにした。その結果2接合素子で14.3%、開放電圧1.57Vまで向上した。以上の結果は今後の薄膜太陽電池系への展開が期待される。
