What is it about?
predicting the efficiency limit of perovskite solar cells by the drift-diffusion model is of critical importance for understanding the device physics and loss mechanisms. we have corrected the expression of the intrinsic radiative recombination considering the light trapping and angular emission angle. Together with the appropriate the choice of the selective contact, we have first predicted the efficiency limit of perovskite solar cells in the framework of the drift-diffusion model.

Perspectives
predicting the efficiency limit of perovskite solar cells by the drift-diffusion model enable the quantification of the efficiency loss by specific loss mechanisms such as trap-assisted non-radiative recombination, surface recombination, injection and extraction barrier etc.
