(author), Wang, Qian (author), Peng, Guoqiang (author), Xu, Youkui (author), Zhang, Haihua (author), Wang, Gang (author), Ding, Liming (author), Jin, Zhiwen (author)Two-dimensional (2D) Dion-Jacobson (D-J)-type cesium lead iodide CsPbI <sub>3</sub> perform remarkably in terms of stability. However, the complex interactions between spacer and inorganic layers limit its excellent progress in perovskite solar cells (PSCs). Herein, starting from the considerable structural diversity of organic spacers, we...journal article 2022

Wang, Shuo (author), Xu, Youkui (author), Wang, Qian (author), Zhou, Xufeng (author), Li, ZhenHua (author), Wang, Meng (author), Lei, Yutian (author), Zhang, Hong (author), Wang, H. (author), Jin, Zhiwen (author)Iodine vacancies and uncoordinated iodide ions of CsPbI<sub>3</sub> films are mainly responsible for nonradiative recombination. Here, we report a composition-engineering passivation method that through guanidium (GA<sup>+</sup>) and I<sup>−</sup> forms strong hydrogen bonds to passivate iodine vacancies and reduce defects. Both experimental...journal article 2022

(author), Li, Xiaogang (author)The atmospheric corrosion of carbon steel was monitored by a Fe/Cu type galvanic corrosion sensor for 34 days. Using a random forest (RF)-based machine learning approach, the impacts of relative humidity, temperature and rainfall were identified to be higher than those of airborne particles, sulfur dioxide, nitrogen dioxide, carbon monoxide...journal article 2020
