The invention discloses a solar cell front grid line structure. The front grid line structure is structurally composed of at least three main grid lines and auxiliary grid lines which are arranged in a mode that a certain angle is reserved between the main grid lines and the auxiliary grid lines; the auxiliary grid lines between the adjacent main grid lines are of a non-continuous structure in the transverse direction, the auxiliary grid lines between the adjacent main grid lines are divided into left auxiliary grid lines and right auxiliary grid lines by a longitudinal partition; the left auxiliary grid lines and the right auxiliary grid lines are in asymmetrical arrangement in the transverse direction; the left ends of the left auxiliary grid lines are connected with the main grid line at the left side of the left auxiliary grid lines, and the right ends of the left auxiliary grid lines are connected in a segmented mode by short grid lines; the right ends of the right auxiliary grid lines are connected with the main grid line at the right side of the right auxiliary grid lines, and the left ends of the right auxiliary grid lines are connected in a segmented mode by short grid lines. Correspondingly, the invention further provides a solar cell applying the front grid line structure and a solar cell module. Adoption of the front grid line structure can effectively reduce the production cost and improve the photoelectric conversion efficiency of solar cells.
Description
technical field [0001] The present invention relates to the grid structure design of front electrode printing in solar cells, more specifically, the present invention relates to a solar cell front grid line structure, solar cells and solar cell components. Background technique [0002] In today's energy shortage situation, solar cells, as a renewable resource, have attracted widespread attention. In recent years, it has been vigorously developed, and large-scale solar cell factories have been established all over the world. While pursuing high conversion efficiency, reducing costs has also become a key point for various manufacturers to improve their competitiveness. [0003] Crystalline silicon solar cells are mainly composed of four parts: front electrode, anti-reflection film, PN junction, and back electrode. The main function of the front electrode is to export the carriers generated by the PN junction by using high-conductivity metals for use by external circuits. Th...
