Abstract: A display device includes a substrate, a thin-film transistor disposed on the substrate, a via insulating layer disposed above the thin-film transistor, a first electrode disposed on the via insulating layer and electrically connected to the thin-film transistor, a pixel-defining layer disposed on the via insulating layer and on the first electrode and that includes an opening that partially exposes an upper surface of the first electrode; and a first swelling prevention layer disposed on one end of the upper surface of the first electrode and interposed between the first electrode and the pixel-defining layer. The pixel-defining layer comprises a first region that overlaps the first swelling prevention layer and the first electrode, and a second region that overlaps the first electrode but not the first swelling prevention layer. The second region of the pixel-defining layer is in direct contact with the upper surface of the first electrode.

Abstract: There is provided a method of producing a photovoltaic device comprising a photoactive region comprising a layer of perovskite material, wherein the layer of perovskite material is disposed on a surface that has a roughness average (Ra) or root mean square roughness (Rrms) of greater than or equal to 50 nm. The method comprises using vapour deposition to deposit a substantially continuous and conformal solid layer comprising one or more initial precursor compounds of the perovskite material, and subsequently treating the solid layer with one or more further precursor compounds to form a substantially continuous and conformal solid layer of the perovskite material on the rough surface. There is also provided a photovoltaic device comprising a photoactive region comprising a layer of perovskite material disposed using the method.
