a J–V, b EQE curves of the optimal G-BHJ OSCs with different active layer thickness. c device performance parameters (PCE, JSC, VOC, and FF) versus the active layer thickness. d Comparison of our results with previously reported PCEs and thickness for both binary and ternary OSCs. The detailed material systems and device parameters of each point are provided in Supplementary Table 12.
