Facile RbBr interface modification improves perovskite solar cell efficiency
From Fig. 3 (a), it is found that the SnO 2 layer has a rough surface 300–400 nm in thickness. From Fig. 3 (b), it is found that RbBr solution is evenly dispersed on the SnO 2 layer, and no obvious RbBr crystals are observed after heating at 150 C for 30 min, which may be because the growth of RbBr crystals requires seeding and induction.
