Fig. 3. Influence of the parameters such as the thickness of each layer of PSCs on their performance. (a) Absorption contour map within the working band, as the thickness of the perovskite layer changes from 450 nm to 900 nm; (b) plot of the percentage stacking area of absorption and reflection of each layer under illumination; (c) contour map of the macroscopic changes in the current-voltage curve, as the electronic lifetime of the perovskite layer increases from 0.0005
