Within five years, the efficiency of perovskite-based solar cells has increased considerably. Meanwhile, the cells convert more than 20% of solar irradiation into electric power. Low material costs and small amounts of material required – thanks to the thin-film technology – make perovskite solar cells a promising alternative. Costs for the conversion of sunlight into electric power can be reduced. A major drawback of the technology, however, is the use of environmentally harmful lead compounds for the production of the perovskite crystals.
