Perovskite solar cells: Possible aspects of high efficiency uncovered
Solar cells based on perovskites have reached enormously high efficiencies within a few years, only. Those containing hybrid halide perovskite, i.e. materials containing inorganic and organic components, achieve particularly high efficiencies, but lack long-term stability, yet. Even though inorganic perovskite…
