Zusammenfassung: | The embodiment of the invention provides a silicon solar cell production method, a silicon wafer and a silicon solar cell piece. The production method of the silicon solar cell comprises the following steps: preparing a silicon wafer; and performing a solar cell piece manufacturing process on the silicon wafer to form a solar cell piece, wherein the solar cell manufacturing process includes a film forming step on the silicon wafer. And the production method of the silicon solar cell further comprise the step of forming a groove for splitting on the silicon wafer before the film forming step, wherein the film forming step includes forming a thin film on one side of the silicon wafer where the groove for splitting is formed. According to the production method, the photoelectric conversion efficiency after the solar cell is split into small pieces can be improved.
