The researchers also built a doped cell with an active area of 1.05 cm2 that achieved a power conversion efficiency of up to 23.9% and showed no degradation after 1,500 h. “With DPPP ...

Inverted perovskite cells have a device structure ... while the HTL was made with [2-(9H-Carbazol-9-yl)ethyl]phosphonic acid (2PACz). A co-adsorbed approach (CA) was used for the SAM application.

reached its closest level to becoming un-inverted in 9-months on Thursday, as the 2s10s curve continues to steepen. The 2s10s curve came up to -14 basis points away from un-inverting, which is the ...
