a A p-i-n inverted planar PSC utilizing the [BMP]+[BF4]− additive to suppress deep trap states, the thermally stable HTL polyTPD, and Cr-modified Au electrode to achieve excellent stability under full sunlight at 85 °C.

Stability of over 9000-h operational tracking was achieved due to localized effect of mesopores and interface strengthening effect of 5-AVAI.
