摘　　要：Previous cost analysis of perovskite solar cells(PSCs)has revealed that the transparent conductive oxide(TCO)substrates account for most of the material cost,emphasizing the need to recover TCO in PSC recycling.However,the conventional use of compact and ultrathin electron transport materials(ETMs)such as TiO_(2)and SnO_(2),poses a challenge to their removal from the substrate,hindering effective PSC recycling.Here,PbSO_(4) nanoparticles with(011)surface were used as ETM to fabricate PSCs.The yielded metallicity on the PbSO_(4) nanoparticle surface promoted extracted electron transport across the nanoparticle surface.A certified efficiency as high as 17.9%for the submodule(204.9 cm^(2))with PbSO_(4) was realized successfully,and the best effi-ciency on a small area(0.1 cm^(2))reached 24.1%.The PbSO_(4) layer was removed effortlessly from the substrate by simple aminoethanol washing to recover the TCO,the most expensive component of PSCs.This work provides a novel strategy to prepare soluble insulator-based ETMs by constructing metallic surfaces of nanoparticles;thus,fabricating efficient and recyclable PSCs.
