Method of fabricating ZnS(O,OH) thin film and thin film solar cell using the same

The present invention includes the steps of preparing a substrate, respectively, a zinc precursor solution and the sulfur precursor solution; The method comprising the zinc precursor and the sulfur precursor solution and the mixture solution was prepared by mixing in the microreactor (micro reactor); By impact spraying the mixture onto a heated substrate to form a thin film; And the thin film a step of heat treatment at a predetermined temperature; including and, by changing the predetermined temperature to control the band gap (band gap) of the thin film, method of producing a zinc sulfide thin film, and this with a thin film solar cell It provides.
