Solar cell and method of manufacturing the same
PendingCN122294638AImprove the effect of current collectionAdjust line styleElectrical batterySolar battery
This application relates to the field of solar cell technology, and more particularly to solar cells and their fabrication methods. The fabrication method of the solar cell includes the steps of: providing a solar cell having a first surface and a second surface disposed opposite to each other; performing a first printing, a second printing, and a third printing on the first surface sequentially; the first printing includes printing main grid lines; the second printing includes printing fine grid lines; and the third printing includes printing harpoon lines and / or border lines. The printing paste used for the third printing is a corrosive paste. This application adds a third printing step to print harpoon lines and border lines on the first surface of the solar cell, thus printing the harpoon lines and border lines separately from the main grid lines. Furthermore, the use of a corrosive paste in the third printing increases the current collection capacity in the harpoon line region, avoids clouding phenomena at the edge areas of the solar cell, and thereby improves the electrochemical performance of the solar cell.
