A solar cell manufacturing method includes forming a first electrode on a substrate, forming a mixed metal layer on the first electrode, forming a light absorbing layer by injecting hydrogen selenide on the entire surface of the mixed metal layer using a gas injection device, and forming a second electrode on the light absorbing layer. Further, the gas injection device includes a gas pipeline, an inner gas pipe positioned in the gas pipeline and having an opening, and a plurality of injection nozzles disposed below the gas pipeline. |
