WebIt has been shown that a passivation layer (such as PCBM) placed on top of a perovskite layer can infiltrate the perovskite layer. This can help passivate grain boundaries, 9,10 as shown in Figure 4. Figure 4. Image showing how passivation layers (in this case PCBM) can seep into the grain boundaries (GB) within the perovskite layer. WebJul 3, 2024 · The passivation layer increases the open circuit voltage of mixed-cation perovskite cells by as much as 80 mV, with champion cells achieving V oc ∼ 1.18 V. As a result, we obtain efficient and stable perovskite solar cells with a steady-state PCE of 20.4% and negligible hysteresis over a large range of scan rates.
