最近，在钙钛矿型太阳能电池中，光子回收已被证明是可测量的。在这里，我们讨论了这种效应对钙钛矿型太阳能电池开路电压的影响，并展示了由于光子循环而产生的电压提升如何依赖于电子性质，如肖克利-里德-霍尔寿命，以及器件的光学性质，如寄生吸收的量和光出耦合的效率。
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.
