Methods For Forming A Perovskite Solar Cell
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.

- 1. A method of forming a perovskite thin film, comprising:
depositing a perovskite layer onto a substrate, and processing the perovskite layer with 1-10 pulses of intense pulsed light, the intense pulsed light having a wavelength of about 150 nm to about 1000 nm, an energy of about 1 J/cm2 to about 35 J/cm2, and each pulse having a duration of about 1 microsecond to about 5 milliseconds; wherein the perovskite layer comprises a mixed halide perovskite formed from a perovskite precursor composition including an alkyl halide having 1 to 20 carbons.
- 9. A method of forming a perovskite thin film, comprising:
depositing a perovskite layer onto a substrate, and processing the perovskite layer with 1-10 pulses of intense pulsed light, the intense pulsed light having a wavelength of about 150 nm to about 1000 nm, an energy of about 1 J/cm2 to about 35 J/cm2, and each pulse having a duration of about 1 microsecond to about 5 milliseconds; wherein the perovskite layer comprises a mixed halide perovskite formed from a perovskite precursor composition including an alkyl halide; wherein the alkyl halide comprises 1 to 20 carbons and the halide is chosen from the group chlorine, bromine, and iodine.
