Electronic-morphological decoupling in mixed-dimensional halide perovskite heterostructures
Mahmoud Samadpour, Alireza Fathi Beiraghvandi, Kazem Meraji +5
Surface morphology is widely considered an indicator of thin-film quality, with smoother films generally expected to exhibit more uniform optoelectronic properties. Here, we demons…

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…

Overcoming Transport Layer Bottlenecks to Quantify Ionic Parameters from Transient Ion Current Measurements of Perovskite Solar Cells
Shudi Jiao, Miguel Torre Cachafeiro, Huagui Lai +7
In perovskite solar cells (PSCs), voltage step-induced transient ion current (TIC) measurements, commonly referred to as bias-assisted charge extraction (BACE), are frequently used…
