Abstract
A coating method for preparing a light absorbing layer of a solar cell is provided. In a non-vacuum environment, an ultrasonic vibrating mixer is employed to mix a CIGS mixture with a mixing fluid to obtain a CIGS coating material. The CIGS coating material is then uniformly coated on a molybdenum (Mo) layer which is driven by a conveyor device, so as to form a CIGS coating material layer having a uniform thickness on the Mo layer. An infrared ray (IR) heating lamp is then used to dry the CIGS coating material layer for removing residue of the mixing fluid remained in the CIGS coating material layer. In such a way, a CIGS light absorbing layer adapted for absorbing a solar energy and converting the absorbed solar energy into an electric energy is obtained. The CIGS light absorbing layer can be then used for fabricating a CIGS solar cell.
