Abstract

The present invention relates to an optoelectronic device comprising: (a) a substrate comprising at least one first electrode, which at least one first electrode comprises a first electrode material, and at least one second electrode, which at least one second electrode comprises a second electrode material; and (b) a photoactive material disposed on the substrate, which photoactive material is in contact with the at least one first electrode and the at least one second electrode, wherein the substrate comprises: a layer of the first electrode material; and, disposed on the layer of the first electrode material, a layer of an insulating material, which layer of an insulating material partially covers the layer of the first electrode material; and, disposed on the layer of the insulating material, the second electrode material, and wherein the photoactive material comprises a crystalline compound, which crystalline compound comprises: one or more first cations selected from metal or metalloid cations; one or more second cations selected from Cs'RB, K, NHand organic cations; and one or more halide or chalcogenide anions. A substrate comprising a first and second electrode and processes are also described.
