摘要
A method of producing nanoparticles of solar light absorbing compound materials based on pulsed laser ablation is disclosed. The method uses irradiation of a target material of solar light absorbing compound material with a pulsed laser beam having a pulse duration of from 10 femtoseconds to 500 picoseconds to ablate the target thereby producing nanoparticles of the target. The nanoparticles are collected and a solution of the nanoparticles is applied to a substrate to produce a thin film solar cell. The method preserves the composition and structural crystalline phase of the starting target. The method is a much lower cost fabrication method for thin film solar cells.
