Enriching conductive capping by alkaline treatment of perovskite quantum dots towards certified 18.3%-efficient solar cells

Nature Communications
Perovskite quantum dots (PQD) hold great promise for next-generation photovoltaics. However, neat ester antisolvents hydrolyze inefficiently into target ligands under ambient conditions, compromising the formation of integral conductive capping on PQD ...
