Assessment of Photon Recycling in Perovskite Solar Cells by Fully Coupled Optoelectronic Simulation

An optical dyadic Green's function framework to describe the transverse electromagnetic fields in a planar perovskite solar-cell stack is coupled an electronic drift-diffusion model for rigorous treatment of photon recycling wave-optics regime realistic photovoltaic device. The provides local reabsorption rate as well detailed-balance compatible radiative prefactor, which are used achieve self-consistent solution that yields full optoelectronic device characteristics. presented approach detailed insights into impact on performance under different regimes charge transport and recombination can help identify various losses nonideal, devices. global efficiency quantified by defining quantum efficiencies reabsorbed radiation, while furthermore be effective prefactor. introduced here guide design future devices exploit potential recycling.
