Shedding light on perovskite films

Perovskite semiconductors are considered promising materials for solar cells of the next generation. Suitability of a semiconductor for photovoltaics is reflected among others by the so-called photoluminescence quantum efficiency. Researchers have now developed a model, by means of which photoluminescence quantum efficiency of perovskite films can be determined exactly for the first time.
