Spray deposited polycrystalline MAPbBr3 thick films for hole-transport-material free solar cells

Chem Commun (Camb). 2022 Apr 21;58(33):5172-5175. doi: 10.1039/d2cc00596d.

Abstract

A spray deposition procedure for the fabrication of polycrystalline MAPbBr3 thick films (20-100 μm) is developed and highly efficient (>5.5% under AM1.5 sunlight) hole-transport-material free perovskite solar cells are successfully made with 40 μm thick MAPbBr3 films.
