Hybrid metal-halide perovskite semiconductors are promising absorber materials for single junction and as well as for tandem solar cells. They have attracted a lot of research attention in recent years, due to the rapid rise of solar cell efficiencies for these materials. Record efficiencies have now reached to above 23 % . Co-evaporation of perovskite thin-films for solar cells offers many advantages such as precise thickness control, pinhole free planar films and compatibility with a large range of different substrates. Efficient co-evaporated solar cells have been demonstrated with different perovskite materials, for example methylammonium lead iodide (MAPbI3) and formamidinium lead iodide (FAPbI3). Furthermore co-evaporation is a promising technique for the upscaling of perovskite solar cells to commercial scales. Some challenges remain, including problems with the process control and relatively small crystallites in the deposited films. Additionally, it is more challenging to achieve mixed compositions with co-evaporation than with solution processing. Here we present recent progress made towards solving these challenges.
