Synergistic stabilization of CsPbI3 inorganic perovskite via 1D capping and secondary growth
文献摘要:
Cesium lead iodide(CsPbI3)perovskite has gained great attention in the photovoltaic(PV)community because of its unique optoelectronic properties,good chemical stability and appropriate bandgap for sun-light harvesting applications.However,compared to solar cells fabricated from organic-inorganic hybrid perovskites,the commercialization of devices based on all-inorganic CsPbI3 perovskites still faces many challenges regarding PV performance and long-term stability.In this work,we discovered that tetrabuty-lammonium bromide(TBABr)post-treatment to CsPbI3 perovskite films could achieve synergistic stabi-lization with both TBA+cation intercalation and Br-doping.Such TBA+cation intercalation leads to one-dimensional capping with TBAPbI3 perovskite formed in situ,while the Br-induced crystal secondary growth helps effectively passivate the defects of CsPbI3 perovskite,thus enhancing the stability.In addi-tion,the incorporation of TBABr can improve energy-level alignment and reduce interfacial charge recombination loss for better device performance.Finally,the highly stable TBABr-treated CsPbI3-based perovskite solar cells show reproducible photovoltaic performance with a champion efficiency up to 19.04%,while retaining 90%of the initial efficiency after 500 h storage without encapsulation.
