Improved reverse bias stability in p–i–n perovskite solar cells with optimized hole transport materials and less reactive electrodes - Nature Energy

AbstractAs perovskite photovoltaics stride towards commercialization, reverse bias degradation in shaded cells that must current match illuminated cells is a serious challenge. Previous research has emphasized the role of iodide and silver oxidation, and the role of hole tunnelling from the electron-transport layer into the perovskite to enable the flow of current under reverse bias in causing degradation.
