2-thiophenemethylammonium bromide (ThMABr; 2-TMABr) is a perovskite precursor used in the preparation of 2D/3D hybrid perovskite solar cells. Using 2-thiophenemethylammonium as the spacer cation results in highly efficient and stable perovskite devices with excellent photovoltaic properties (Zhou et al., 2019).
Greatcell Solar Materials offers diverse thiophene methylammonium-salts enabling researchers to explore the effect of different halide counter ions on the properties of perovskite-based opto-electronic devices. Greatcell Solar Materials’ 2-thiophenemethylammonium bromide is of the highest purity affording consistent results and optimal performance.
