Abstract

Stability is the critical issue in perovskite solar cell, one possible reason of degradation come from organic transport layers which we have used. Recently, we have adopted all metal oxide layers as the charge transport layers, which has significantly improved the device stability. The improvement come from the avoid the interfacial degradation and also the reaction between perovskite and metal electrode, such as Ag and Al. We showed the device with the efficiency of 16.1% and good stability in ambient air.
