High-efficiency n–i–p perovskite solar cells generally incorporate organic hole-transport layer materials such as spiro-OMeTAD or PTAA, which have intrinsically low charge carrier mobility and therefore require doping to improve transport properties. However, using dopants is known affect badly the operational stability of cells. Therefore, development suitable dopant-free critical issue for realizing with high efficiency long lifetimes. Herein, a series small molecules triazatruxene,...
New conjugated (BDT-TTBTBTT) n copolymers are featured as promising hole-transport materials for n–i–p perovskite solar cells delivering efficiencies of up to ∼19%.
Efficient and economic oxidative polymerization enables the synthesis of polytriarylamines (PTAAs), which show comparable performances to high-cost commercial PTAAs in perovskite solar cells delivering efficiencies 18–20%.
