In-Depth Analysis on the Fabry-Perot Effect of Cs₂AgBiBr₆ Double Perovskite-Based Solar Cells via Optical Path Length Modulation

Figure 10

Charge carrier generation rate at different positions within the absorption layer of a Cs₂AgBiBr₆ double perovskite-based solar cell under the different monochromatic lights. (a) 520 nm, (b) 572 nm, and (c) 620 nm. Black and red spectra indicate the charge generation distribution within the absorption layer without and with Au electrode, respectively.
