SnO₂ quantum dots (QDs) ended with chlorine ions are introduced at the interface of spin-coated TiO₂ electron selective layer (ESL)/perovskite to fill the pinholes in the layer and passivate the trapping defects. As a result of the increased interface electron collection and reduced bulk recombination, the planar perovskite solar cell with the QDs modified ESL gives the large power conversion efficiency enhancement from 14.9% to 17.3% and greatly improved stability under the continuous light irradiation.

氯封端的 SnO2 量子点修饰的 TiO2 电子选择层可提高平面钙钛矿太阳能电池的性能

_{在旋涂的TiO 2}电子选择层（ESL）/钙钛矿的界面处引入以氯离子结尾的SnO ₂量子点（QD）以填充层中的针孔并钝化捕获缺陷。由于增加了界面电子收集并减少了体复合，具有 QDs 改性 ESL 的平面钙钛矿太阳能电池将功率转换效率从 14.9% 提高到 17.3%，并且在连续光照射下大大提高了稳定性。
