Abstract:
1. A manufacturing method of a solar cell, and the solar cell comprising a wafer, and first and second electrode layers having a different polarity from one another, and the manufacturing method forming a base portion of the two electrode layers on a same side of the wafer by a vapor deposition process, and the two electrode layers having an interval apart, wherein the vapor deposition process includes a first mask layer, and the first mask layer includes a plurality of first apertures, and the first mask layer is placed on a side of the wafer for performing a vapor deposition process, such that the wafer includes a first electrode base disposed at a position opposite to each first aperture of the first mask layer, wherein the wafer is formed on the same side of the first electrode base, and a second mask layer having a plurality of second apertures is used for depositing a second electrode base adjacent to the first electrode base wherein the first apertures are not juxtaposed with the second apertures with respect to the wafer.
