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…
