A composite photoalignment layer for aligning liquid crystal molecules includes: a monomeric material; a photoinitiator or a thermal initiator; and an azo dye material. A method for preparing a composite photoalignment layer for aligning liquid crystal molecules includes: mixing, in solution form, a monomeric material, a photoinitiator or a thermal initiator, and an azo dye material; coating the mixed solution onto a substrate to form a thin film; exposing the thin film to polarized light; and, with a thermal initiator, heating the thin film to polymerize the monomeric material and form a solid thin film.

A method of fabricating a hybrid organic-inorganic halide perovskite film includes depositing a precursor layer onto a substrate, the precursor layer comprising metal halide, placing an organic source-material layer onto a boat, the organic source-material layer comprising an organic cation, and annealing the precursor layer and the organic source-material layer in a vacuum chamber enclosed in a constrained volume.
