Abstract

In this work, a MAPbBr₃ quantum dot (QD-MAPbBr₃) layer was prepared by a simple and rapid method. Octylammonium bromide (OABr) gives the MAPbBr₃ better exciton binding energy, good surface morphology, and stability. To form a nanocrystalline thin film on indium tin oxide (ITO) glass, the QD-MAPbBr₃ film was coated by a spin-coating method in a nitrogen-filled glove box and the NiO_x film was used as an adhesive layer and hole transport layer. The highest transmittance of MAPbBr₃ on NiO_x/ITO glass was around 75% at 700 nm. This study also reported a high transparent and perovskite bulk-free ITO/NiO_x/QD-MAPbBr₃/C₆₀/Ag solar cell where the NiO_x, QD-MAPbBr₃, and C₆₀ were used as a hole transport layer, active layer, and electron transport layer, respectively.
