Guanidinium bromide

  • Guanidinium-doped perovskites can be obtained using a guanidinium bromide (GABr; GuaBr; CAS Number: 19244-98-5) solution resulting in highly efficient solar cells (Chen et al., 2019; Zhang et al., 2019). Doping of guanidinium bromide into perovskite quantum dots also results in a highly stable and luminescent device (Cha et al., 2020).

    Borun New Material - ChemBorun' Guanidinium Bromide with a purity level of >99% has a superior quality thanks to a reproducible production process and an extremely low moisture content.
