Divergent Solid-state Conversion Pathways in Evaporated All-perovskite Tandem Solar Cells

Huagui Lai, Amber Wright, Nick Huber +8

Sequential thermal evaporation (sTE) is emerging as a solvent-free route to high-quality mid-bandgap perovskites, but its extension to mixed-halide wide-bandgap (WBG) and Sn-Pb nar…
