Impact of Photon Recycling on the Open-Circuit Voltage of Metal Halide Perovskite Solar Cells

Photon recycling has been recently shown to be measurable in perovskite solar cells. Here we discuss the impact of this effect on the open-circuit voltage of perovskite solar cells and show how the voltage boost due to photon recycling depends on electronic properties, such as Shockley-Read-Hall lifetimes, and on the optical properties of the device, such as the amount of parasitic absorption and the efficiency of light outcoupling.
