Stable 6H organic-inorganic hybrid lead perovskite and competitive formation of 6H and 3C perovskite structure with mixed A cations
Abstract
We report the synthesis and properties of a new organic–inorganic hybrid lead perovskite (OIHP), azetidinium lead bromide (AzPbBr<sub>3</sub>), possessing the 6H perovskite structure (space group <i>P</i>6<sub>3</sub>/<i>mmc</i> with <i>a</i> = 8.745 Å and <i>c</i> = 21.329 Å). This compound has a band gap of 2.81 eV and remains stable for >6 months in the ambient environment. DFT simulations are in fairly good agreement with experiments and indicate that AzPbBr<sub>3</sub> is a direct band gap semiconductor. A partial solid solution with the cubic (3C) perovskite methylammonium lead bromide (Az<sub>1–<i>x</i></sub>MA<sub><i>x</i></sub>PbBr<sub>3</sub>) is possible. In Az-rich 6H compositions the lattice volume and band gap are invariant with <i>x</i> (≤0.3), whereas in the MA-rich 3C phase (0.8 ≤ <i>x</i> ≤ 1.0) the lattice parameters and band gap increase with increasing Az content. Although the relatively large band gap of AzPbBr<sub>3</sub> makes it unsuitable for photovoltaic applications, the results indicate Az<sup>+</sup> is a suitable alternative organic A cation for band gap tuning of OHIPs.
