Despite owing high PCE, these perovskite solar cells (PSC) are limited at commercial scale due to presence of toxic elements such as lead (Pb). At present, tin (Sn) based PSC has emerged as a potential candidate to substitute Pb-based PSCs exhibiting PCE above 12%. In this article, ...
近日,北京大学徐东升教授和梁永齐博士(共同通讯作者)在Advanced Functional Materials上发表了题为“SnO2-C60 Pyrrolidine Tris‐Acid (CPTA) as the Electron Transport Layer for Highly Efficient and Stable Planar Sn-Based Perovskite Solar Cells”的文章。本文作者发现Sn基钙钛矿平面太阳能电池中,极性富勒烯(CPTA)...
However, it is difficult to prepare a Sn-based perovskite film with both robust ferroelectric and semiconductor properties. Here, by doping with 2-methylbenzimidazole, Sn-based perovskite [93.3 mol% (FA0.86Cs0.14)SnI3 and 6.7 mol% PEA2SnI4] semiconductor films are transformed into ...

Hsu et al. demonstrated that using ethylammonium iodide (EAI) as additive significantly improve the crystallinity of the lead-based 3D perovskite films as well as the device performance [26]. So far, there has been no reports on using EAI as additive in tin based HPSCs. Herein, we succeed...
Green hydrogen production using Sn(II)-perovskite materials (Image for representation purpose only) A study led by Flinders University has discovered a novel solar cell process for enhancing green hydrogen production. This innovation uses a new class of kinetically stable “core and shell Sn(II)-pe...
In this talk, I would like to introduce a general overview and recent progress of our group of p-type Sn-based metal halide perovskites for the application of field-effect transistors (FETs). In the first part of the talk, I will mainly address inorganic perovskite thin-film transistors ...
Thecommercial feasibility of perovskite solar cells (PSCs) isnot guaranteed as long as lead (Pb) is present in the active material,halide perovskites. Mixed halide tin (Sn)-based alloyed perovskiteswith optimal band gaps ranging from 1.15 to 3.55 eV are excellentalternatives to Pb-based perovskit...
