In the quest for better solar panels, we continue to refine our understanding of the physics of photovoltaic absorbers, such as hybrid metal-organic perovskites. By scrutinizing photoluminescence transients, the authors explain how to determine fundamental semiconductor properties and estimate the potential open-circuit voltage of perovskite thin films. Additionally, they highlight the impacts of photon recycling, doping, and bulk and surface recombination of charge carriers on device performance.
