Outline of Research at the Start

ペロブスカイト太陽電池の開発では,デバイスの光電変換効率のさらなる向上と耐久性の飛躍的な向上が依然課題となっている.本研究では,ペロブスカイト層からの正孔を回収する材料に着目し,マルチポッド型正孔回収単分子膜材料の開発に取り組む.これらの単分子膜材料では,上下のペロブスカイト層および電極基板のそれぞれに対して face-on に配向制御できるため,効率的な電荷回収が可能であり光電変換効率の向上が期待できる.この革新的な単分子膜材料の開発により,これまで有機半導体材料の欠点に由来していた導電性や耐久性などの課題を解決し,ペロブスカイト太陽電池の長期耐久性と高い光電変換効率(>23%)を実現する.

Outline of Final Research Achievements

Hole-collecting monolayers have significantly advanced the performance of inverted perovskite solar cells. However, to date, all of the reported monolayer materials have only one anchoring group, align edge-on to the adjacent substrate, and show low wettability. In this work, we developed face-on oriented multipodal monolayer materials based on triazatruxene derivatives bearing multiple phosphonic acid anchoring groups. The face-on oriented tripodal material was found to facilitate hole extraction, leading to perovskite solar cells with enhanced stability and high power conversion efficiencies up to 23.0%. In addition, to improve the surface wettability of the monolayer, we also developed tetrapodal molecules by introducing four phosphonic anchoring groups into a saddle-like cyclooctatetraene skeleton. We found that the tetrapodal molecules can adsorb on the electrode surface with some phosphonic groups pointing upward, leading to a hydrophilic surface and improved wettability.

Academic Significance and Societal Importance of the Research Achievements

ペロブスカイト太陽電池の分野において,これまでにほとんどの正孔回収材料がバルクの厚膜層として用いられてきた.しかし,正孔回収材料自体の厚膜による光吸収が取り出せる電流密度を低下させてしまい,又、この厚膜のモルフォロジーの安定性がデバイス自体の低い熱安定性の原因となっている.これに対して,本研究ではマルチポッド型構造をもつ単分子膜材料の配向配列制御による各層の界面の精密制御を実証し,太陽電池の高効率化・高耐久性化を達成した.マルチポッド型の有用性を実証することにより,本太陽電池の開発分野に多大なインパクトをもたらすとともに,その実用化を大きく加速できるものと期待できる.
