Abstract
The invention provides a method for manufacturing a solar cell, and relates to the field of semiconductor technology. The method comprises: laser cutting a electrode layer arranged on one side of theflexible substrate to obtain a plurality of spaced back electrodes; performing a first mechanical cutting on a fabricated high-impedance layer, a buffer layer and an absorbing layer to form a plurality of spaced areas; performing a second mechanical cutting on a fabricated low-impedance layer, the high-impedance layer, the buffer layer, and the absorbing layer to obtain a plurality of battery cells. The low-impedance layer of one of the adjacent two battery cells is arranged in contact with the back electrode of the other battery cell through the corresponding spaced area, so that the adjacenttwo battery cells are connected in series. With the above arrangement, the method can reduce the manufacturing cost and prolong the service life of the solar cells manufactured by the prior art.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a method for manufacturing a solar cell. Background technique [0002] As a renewable and clean energy, solar energy has been widely concerned. Among them, solar cells manufactured by semiconductor technology are used as a common device for solar energy applications due to their photoelectric conversion properties. Also, a solar cell is generally composed of a plurality of battery cells. Considering the reduction of the output voltage of a single battery cell, generally a plurality of battery cells are connected in series to increase the output voltage of the solar cell. [0003] The inventors have found through research that in the prior art, the conductive silver paste is screen-printed on the outside of the prepared solar cells to connect the battery cells in series. This method can ensure that the overall output voltage of the solar cell meets the power supply requi...
