Highly Efficient 2D/3D Mixed-Dimensional Cs₂PbI₂Cl₂/CsPbI_2.5Br_0.5 Perovskite Solar Cells Prepared by Methanol/Isopropanol Treatment.

ABSTRACT: All-inorganic perovskite solar cells are attractive photovoltaic devices because of their excellent optoelectronic performance and thermal stability. Unfortunately, the currently used efficient inorganic perovskite materials can spontaneously transform into undesirable phases without light-absorption properties. Studies have been carried out to stabilize all-inorganic perovskite by mixing low-dimensional perovskite. Compared with organic two-dimensional (2D) perovskite, inorganic 2D Cs₂PbI₂Cl₂ shows superior thermal stability. Our group has successfully fabricated 2D/3D mixed-dimensional Cs₂PbI₂Cl₂/CsPbI_2.5Br_0.5 films with increasing phase stability. The high boiling point of dimethyl sulfoxide (DMSO) m
