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%.

Elastic perovskite solar cells, for the first time, have been realized by designing a stretchable nanostructured fiber and spring-like modified Ti wire as two electrodes with perovskite materials coated on the modified Ti wire through a solution process. The elastic perovskite solar cell appears in a fiber format and maintains stable energy conversion efficiencies under stretching.

In the process of preparing CsPbBr3 films by two-step or multi-step methods, due to the low solubility of CsBr in organic solvents, the prepared perovskite films often have a large number of holes, which is definitely not conducive to the performance of CsPbBr3 perovskite solar cells (PSCs). In response to this problem, this article proposed a method of introducing InBr3 into the PbBr2 precursor to prepare a porous PbBr2 film to increase the reaction efficiency between CsBr and PbBr2 and achieve the purpose of In (Ⅲ) incorporation, which not only optimized the morphology of the produced CsPbBr3 film but also enhanced the charge extraction and transport capabilities, which was ascribed to the reduction of the trap state density and impurity phases in the perovskite films, improving the performance of CsPbBr3 PSCs. At the optimal InBr3 concentration of 0.21 M, the InBr3:CsPbBr3 perovskite solar cell exhibited a power conversion efficiency of 6.48%, which was significantly higher than that of the pristine device.
