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…
Triple-cation perovskite solar cells fabricated by hybrid PVD/blade coating process using green solvents
Severin Siegrist, Shih-Chi Yang, Evgeniia Gilshtein +3
The scalability of highly efficient organic-inorganic perovskite solar cells (PSCs) is one of the remaining challenges of solar module manufacturing. Various scalable methods have…
Flexible perovskite/Cu(In,Ga)Se2 monolithic tandem solar cells
Fan Fu, Shiro Nishiwaki, Jeremie Werner +6
We report a proof-of-concept two-terminal perovskite/Cu(In, Ga)Se2 (CIGS) monolithic thin-film tandem solar cell grown on ultra-thin (30-microns thick), light-weight, and flexible…
