Ethylammonium bromide, high purity perovskite precursor

Used to alter properties of perovskite materials to improve efficiency of hybrid electronic devices


Ethylammonium bromide (EABr) has been used as a precursor for the alteration of crystallite structure, evolution of film morphology, and fine-tuning optical properties of perovskite materials to improve the efficiency of hybrid electronic devices.

Sky-blue layered perovskite light-emitting devices showing the maximum EQE of 2.6% and power efficiency of 1 lm/W at 100 cd/m2 have been achieved [1], with a device structure of ITO/PEDOT:PSS/ (EA)2(MA)n−1PbnBr3n+1 (50 nm)/TmPyPB (50 nm)/CsF/Al.
