The benefits of vacuum processed perovskite solar cells will be discussed. Different vacuum based methods are used ranging from thermal co-sublimation, close-space sublimation and vapor assisted flash evaporation.
I will also discuss the benefit of using these perovskites in substrate configuration as well as semitransparent cells for bifacial operation and for building integrated PV. The use of sublimed perovskite in perovskite-silicon tandem cells using fully textured Si bottom cells will be presented, including methods to identify the shortcomings of these tandem cells.
Using a home build setup to determine the stability for both indoor and outdoor applications we are able to monitor the solar cells stability. First results on outdoor and indoor stability measurements will also be presented demonstrating the importance of encapsulation methods. Best devices have a T95 over 1000 hours mpp at 75 degrees C and 1 sun illumination.
