ABSTRACT:
The present invention discloses a method of manufacturing a solar cell by forming two electrode layers on the same side of a wafer, and avoiding sunlight incident to another side from being blocked by the electrode layers to enhance the photoelectric conversion efficiency, and each electrode layer is formed by using a mask layer to perform a vapor deposition process, without requiring any mask lithography or etching process. Of course, the issue of a high-temperature process that deteriorates the quality of the wafer no longer exists.
