The stability of encapsulated planar-structured CH3NH3PbI3 (MAPbI(3)) perovskite solar cells (PSCs) was investigated under various simulated environmental conditions. The tests were performed under approximately one sun (100 mW cm(-2)) illumination, varying temperature (up to 85 degrees C cell temperature) and humidity (up to 80%). The application of advanced sealing techniques improved the device stability, but all devices showed significant degradation after prolonged aging at high temperature and humidity. The degradation mechanism was studied by post-mortem analysis of the disassembled cells using SEM and XRD. This revealed that the degradation was mainly due to the decomposition of MAPbI(3), as a result of reaction with H2O, and the subsequent reaction of hydroiodic acid, formed during MAPbI(3) decomposition, with the silver back contact electrode layer.
