n-Butylammonium bromide

• 
  Recent research has found that aliphatic bulky alkylammonium cations such n-butylammonium, i-butylammonium, t-butylammonium, can be used as organic Spacers between inorganic sheets to form quasi-2D perovskites. Duong et al. (2020) used n-butylammonium bromide (n-BABr; CAS Number: 15567-09-6) as a 2D precursor to fabricate highly performant perovskite-silicon tandem solar cells achieving record efficiencies. Use Borun New Material - ChemBorun's high quality n-butylammonium bromide (purity level > 99%) for ultimate device performance.
