WebMay 1, 2024 · CsPbI 3 has four different kinds of phases (cubic (α), tetragonal (β), and two orthorhombic phases (a metastable black γ and a non-perovskite yellow δ-phase)) [26, 27 ]. At the room temperature (RT), black phase based CsPbI 3 tends to spontaneously transform to non-perovskite yellow phase with an undesirable bandgap of 3.01 eV [ 28, 29 ]. WebOct 27, 2024 · CsPbI 3 QDs, with a tunable bandgap between 1.75 and 2.13 eV, are an ideal top cell candidate for all-perovskite multijunction solar cells because of their demonstrated small V OC deficit. We show that charge carrier mobility within perovskite QD films is dictated by the chemical conditions at the QD-QD junctions.
