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…
Stabilizing Solution-Substrate Interaction of Perovskite Ink on PEDOT:PSS for Scalable Blade Coated Narrow Bandgap Perovskite Solar Modules by Gas Quenching
Severin Siegrist, Johnpaul K. Pious, Huagui Lai +5
The development of scalable 1.25 eV mixed Pb-Sn perovskite solar modules by blade coating lags behind Pb-based perovskites due to limited understanding of solution-substrate intera…
Unveiling the GeI2-Assisted Oriented Growth of Perovskite Crystallite for High-Performance Flexible Sn Perovskite Solar Cells
Huagui Lai, Selina Olthof, Shengqiang Ren +7
Tin perovskites are emerging as promising alternatives to their lead-based counterparts for high-performance and flexible perovskite solar cells (PSCs). However, their rapid crysta…
Revealing the role of tin fluoride additive in narrow bandgap Pb-Sn perovskites for highly efficient flexible all-perovskite tandem cells
Johnpaul K. Pious, Yannick Zwirner, Huagui Lai +11
Tin fluoride (SnF2) is an indispensable additive for high-efficiency Pb-Sn perovskite solar cells (PSCs). However, the spatial distribution of SnF2 in the perovskite absorber is se…
Resolving oxidation states and Sn-halide interactions of perovskites through Auger parameter analysis in XPS
Alexander Wieczorek, Huagui Lai, Johnpaul Pious +2
Reliable chemical state analysis of Sn semiconductors by XPS is hindered by the marginal observed shift in the Sn 3d region. For hybrid Sn-based perovskites especially, errors asso…
High-Performance Flexible All-Perovskite Tandem Solar Cells with Reduced VOC-Deficit in Wide-Bandgap Subcell
Huagui Lai, Jincheng Luo, Yannick Zwirner +22
Among various types of perovskite-based tandem solar cells (TSCs), all-perovskite TSCs are of particular attractiveness for building- and vehicle-integrated photovoltaics, or space…
