Thermal evaporation is a promising deposition technique to scale up perovskite solar cells (PSCs) to large areas, but the lack of understanding of the mechanisms that lead to high quality evaporated methylammonium lead triiodide (MAPbI3) films gives rise to devices with efficiencies lower than those obtained by spin coating.
In this paper the researchers investigate the role of Sr and Ca additives to CsFA-PbI solar cells on performance.
Litos Lite was used to perform JV scan under 1 sun illumination.
