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).
