Abstract
A novel 2D halide perovskite with stoichiometric quantities of Cu<sup>+</sup>, Cu<sup>2+</sup>, and In<sup>3+</sup> in the inorganic slabs shows emergent properties not seen in Cu<sup>II</sup> or Cu<sup>I</sup>–In<sup>III</sup> perovskites, including enhanced visible-light absorption and electronic conductivity.
