The publication "Efficient Perovskite Solar Cells over a Broad Temperature Window: The Role of the Charge Carrier Extraction" by the Loi group has been featured on the back cover of Advanced Energy Materials. The article shows a systematical investigation of the mechanism behind the temperature dependence of the device performance in hybrid perovskite solar cells (HPSCs). They show that the temperature dependence of the performance of hybrid perovskite solar cells is dominated by the electron transport capability of the electron-extracting layer. Loi and colleagues further demonstrate efficient hybrid perovskite solar cells over a temperature range from 295 K to 160 K by n-doping the PCBM electron-extracting layer or using a fullerene derivative with intrinsically higher electron transport capability.
