Abstract

Two-dimensional halide perovskites are provided. The perovskites have two-dimensional Dion-Jacobson phases and are composed of a plurality of inorganic perovskite layers separated by 3-(aminomethyl)piperidinium (3AMP) and/or 4-(aminomethyl)piperidinium (4AMP) spacer cations. The halide perovskites may have a single perovskitizer cation or mixed perovskitizer cations. Also provided are radiation-absorbing materials comprising the perovskites and photovoltaic cells comprising the radiation-absorbing materials as photoactive materials.
