The temperature dependence of the principal photovoltaic parameters of perovskite photovoltaics is studied. The recombination activation energy is in good agreement with the perovskite's bandgap energy, thereby placing an upper bound on the open-circuit voltage. The photocurrent increases moderately with temperature and remains high at low temperature, reinforcing that the cells are not hindered by insufficient thermally activated mobility or carrier trapping by deep defects.
研究了钙钛矿光伏的主要光伏参数的温度依赖性。复合激活能与钙钛矿的能带隙能量很好地吻合，从而对开路电压施加了上限。光电流随温度适度增加，并在低温下保持较高水平，这表明电池不受热激活迁移率不足或深缺陷载流子捕获的限制。
