If perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs) are to be commercialized, they must achieve long-term stability, which is usually assessed accelerated degradation tests. One of the persistent obstacles for PSCs has been successfully passing damp-heat test (85°C and 85% relative humidity), standard verifying stability commercial photovoltaic (PV) modules. We fabricated damp heat-stable by tailoring dimensional fragments two-dimensional layers formed at room temperature oleylammonium iodide molecules; these passivate surface electron-selective contact.

P-i-n geometry perovskite solar cells (PSCs) offer simplified fabrication, greater amenability to charge extraction layers, and low-temperature processing over n-i-p counterparts. Self-assembled monolayers (SAMs) can enhance the performance of p-i-n PSCs but ultrathin SAMs be thermally unstable. We report a robust hole-selective layer comprised nickel oxide (NiOx) nanoparticle film with surface-anchored (4-(3,11-dimethoxy-7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid (MeO-4PADBC) SAM that improve stabilize NiOx/perovskite interface.
