Figure 8
SEM cross-section image (left) and PV characteristics (AM1.5, 100 mW/cm²) of MBI perovskite solar cell (right), fabricated using MBI layer deposited by CVD (50 °C substrate temperature, MAI/BiI3 ratio of 5 and 225 nm layer thickness). Average and standard deviation based on 5 devices. Characteristics of the best performing solar cell are shown in parentheses.
