Abstract: Methods of forming a perovskite-containing film comprising depositing one or more metal oxide layers onto a substrate; and irradiating each metal oxide layer with a UV LED light source after deposition to sinter and/or anneal a target metal oxide in the one or more metal oxide layers without damaging the underlying substrate or perovskite material. The LED light source can be selected to emit a narrow spectral width of pulsed radiation. The radiation emitted can consist essentially of wavelengths within 20 nm of the wavelength of maximum absorbance (λmax) of the target metal oxide, that is, wavelength from UV LED can be λmax±20 nm, to achieve layer-specific annealing and sintering of metal oxide charge transport layer. The target metal oxide can include tin oxide in the electron transport layer or nickel oxide in the hole transport layer. Perovskite-containing films formed from the methods described herein are also disclosed.
