Low Bandgap

Vacuum-assisted thermal annealing not only could improve film morphology and crystallinity, but also could accelerate the sublimation of undesired MACl. With the help of this process, we obtain a highly efficient low-bandgap CH3NH3Sn0.5Pb0.5IxCl3−x perovskite solar cell with a power conversion efficiency of 12.3%.
