摘要 Interfacial engineering has made an outstanding contribution to the development of high-efficiency perovskite solar cells(PSCs).Here,we introduce an effective interface passivation strategy via methoxysilane molecules with different terminal groups.The power conversion efficiency(PCE)has increased from 20.97%to 21.97%after introducing a 3-isocyanatopropyltrimethoxy silane(IPTMS)molecule with carbonyl group,while a trimethoxy[3-(phenylamino)propyl]silane(PAPMS)molecule containing aniline group deteriorates the photovoltaic performance as a consequence of decreased open circuit voltage.The improved performance after IPTMS treatment is ascribed to the suppression of non-radiative recombination and enhancement of carrier transportation.In addition,the devices with carbonyl group modification exhibit outstanding thermal stability,which maintain 90%of its initial PCE after 1500 h exposure.This work provides a guideline for the design of passivation molecules aiming to deliver the efficiency and thermal stability simultaneously.
