Figure 3 | Photovoltaic performance of mixed PSCs.

Caption

a,b The experimental (a) and simulated (b) J-V curves of the mixed PSCs modified with different 2-D flakes on perovskite GBs. c The simulated device efficiencies of mixed PSCs with varying mobilities of 2-D flakes. The three regions (I, II, III) correspond to the carrier mobilities of the three different 2-D flakes (GO, MoS2, BP), and the star symbols represent the experimental efficiencies of PSCs modified with three different 2-D flakes in 6a. d Simulated device PCEs and efficiency enhancement for BP flakes located at different positions on perovskite grains.
