Long-lived hot-carrier light emission and large blue shift in formamidinium tin triiodide perovskites
Hot carriers have excess energy that could be used to enhance solar cell efficiencies if their lifetimes are sufficiently long. Here, Fang et al. observe nanosecond hot carrier lifetime by photoluminescence in formamidinium tin triiodide perovskites which is 1000 times higher than lead based perovsk...

| Sumario: | Hot carriers have excess energy that could be used to enhance solar cell efficiencies if their lifetimes are sufficiently long. Here, Fang et al. observe nanosecond hot carrier lifetime by photoluminescence in formamidinium tin triiodide perovskites which is 1000 times higher than lead based perovskites. |
