Antioxidant Grain Passivation for Air-Stable Tin-Based Perovskite Solar Cells
Qidong Tai,Xuyun Guo,Guanqi Tang,Peng You,Tsz-Wai Ng,Dong Shen,Jiupeng Cao,Chun Ki Liu,Naixiang Wang,Ye Zhu,Chun-Sing Lee,Feng Yan +11 more
TL;DR: The fabrication of air-stable FASnI3 solar cells is reported by introducing hydroxybenzene sulfonic acid or its salt as an antioxidant additive into the perovskite precursor solution along with excess SnCl2 along with the interaction between the sulfonate group and the Sn2+ ion.

Tianyue Wang,Qidong Tai,Xuyun Guo,Jiupeng Cao,Chun Ki Liu,Naixiang Wang,Dong Shen,Ye Zhu,Chun-Sing Lee,Feng Yan +9 more
TL;DR: In this paper, the stability of tin halide perovskites is maintained by adding extra SnX2 (X = F, Cl, or Br) in the precursor solution to inh...
Journal ArticleDOI
Sn-Based Perovskite for Highly Sensitive Photodetectors.
TL;DR: A low‐voltage and high‐performance photodetector based on a single layer of lead‐free Sn‐based perovskite film is reported, showing broadband response from ultraviolet to near‐infrared light and a high gain at a low operating voltage.
