A perovskite thin film and method of forming a perovskite thin film are provided. The perovskite thin film includes a substrate, a hole blocking/electron transport layer, and a sintered perovskite layer. The method of forming the perovskite solar cell includes depositing a perovskite layer onto a substrate and processing (for example, by sintering) the perovskite layer with intense pulsed light to initiate a radiative thermal response that is enabled by an alkyl halide additive.

An EL display panel fabricated by evaporation creates red, green, and blue pixels using a fine deposition mask (251). However, the displacement of the fine deposition mask (251) decreases the manufacturing yield. In the present invention, red, green, and blue pixel electrodes are arranged in a matrix on a TFT substrate (52). The TFT substrate (52) is transferred into a vacuum deposition chamber (56). A light-emitting layer made up of a host material and a red guest material is codeposited on the presentation screen of the TFT substrate using an organic evaporation source (66) in a vacuum. A laser device (58) generates ultraviolet laser light (59) which is guided into the vacuum deposition chamber (56) through a laser window (63) to irradiate a light-emitting layer formed on the green and blue pixel electrodes. The positions of the green and blue pixels are selected by controlling a galvano mirror (62).
