We present a dual passivation approach for p–i–n perovskite solar cells using phenethylammonium chloride that simultaneously passivates defects at the grain boundaries and the perovskite/C 60 interface, thus substantially enhancing both V OC and FF.

Two birds with one stone: dual grain-boundary and interface passivation enables &gt;22% efficient inverted methylammonium-free perovskite solar cells
