抄録/ポイント： 結晶配向はペロブスカイト膜の性質と結果としての素子性能に大きな影響を及ぼす。現在まで,混合カチオンペロブスカイトにおける結晶配向(優先結晶面と特定面に関する結晶積層モード)の精巧な制御は限られた成功を受けており,素子性能を支配する基礎となる機構はまだ明らかではない。ここでは,ホルムアミジニウム/メチルアンモニウム(FA/MA)混合カチオンペロブスカイトにおける熱力学的に有利な結晶配向を,組成工学により微細に調整した。密度汎関数理論計算は,FA/MA比が混合ペロブスカイトの表面エネルギーに影響を及ぼし,結果的に優先配向の変化をもたらすことを明らかにした。基板に平行に横たわると(001)結晶面に沿った好ましい成長はそれらの電荷輸送と収集特性に影響する。最適条件下で,混合カチオンペロブスカイト(FA_1-_xMA_xPbI_2.87Br_0.13(Cl))太陽電池は21%以上のチャンピオン電力変換効率を示し,認証効率は20.50±0.50%であった。本研究は,混合カチオンペロブスカイトの固有の特性を理解する上で重要なステップを提供するだけでなく,ペロブスカイト光エレクトロニクスにおける更なる研究と応用のための基礎を築く。Copyright 2019 Wiley Publishing Japan K.K.
