In 2019,ACS Energy Letters included an article by Ren, Ming; Wang, Jianan; Xie, Xinrui; Zhang, Jing; Wang, Peng. Safety of Bis(4-methoxyphenyl)amine. The article was titled 《Double-Helicene-Based Hole-Transporter for Perovskite Solar Cells with 22% Efficiency and Operation Durability》. The information in the text is summarized as follows:
Amelioration of the mobility and, in particular, the thermal stability of a hole-transporting mol. semiconductor is a practicable strategy to attain the enhancement of both power conversion efficiency (PCE) and operational durability of perovskite solar cells (PSCs). Here, a cost-effective double-[4]helicene-based mol. semiconductor (DBC-OMeDPA) is synthesized for a solution-deposited thin film, exhibiting an improved hole mobility in comparison with state-of-the-art spiro-OMeTAD control. X-ray crystallog. anal. and theor. calculation reveal the 3-dimensional mol. stacking and multidirectional hole-transporting property of DBC-OMeDPA, clarifying the microscopic mechanism of the hole-transport process. A better PCE of 22% at the AM 1.5G conditions is achieved for PSCs with DBC-OMeDPA as the hole-transporter. PSCs using DBC-OMeDPA characteristic of an elevated intrinsic glass transition temperature of 154° maintain a stable PCE output for hundreds of hours at 60° under equivalent full sunglight soaking.Bis(4-methoxyphenyl)amine(cas: 101-70-2Safety of Bis(4-methoxyphenyl)amine) was used in this study.
