Method for improving solar cell efficiency through metal electrode pattern optimization

摘要

The present invention relates to a method of increasing the efficiency of a solar cell by optimizing the shape of the metal electrode when manufacturing a solar cell using a semiconductor. In order to improve the photoelectric conversion efficiency when manufacturing a solar cell using a semiconductor, the optimal metal electrode shape design on the front of the solar cell is made of a finger-shaped grid with a metal electrode shape on the front surface where the sunlight is incident, but the width of the grid is 0.1. It is ~ 1μm and the number of grids is set so that the area of the entire metal electrode is 8-10% of the total area of the solar cell, the gap between grids is constant in designing the grid, and the connecting line connecting the grid A method of improving the efficiency of a solar cell is proposed by optimizing a metal electrode pattern which maximizes the photoelectric conversion efficiency of the solar cell by designing the horizontal grid line and the center to be connected in parallel.
