technical field

The utility model relates to the field of photovoltaic cells, in particular to an electrode structure of a crystalline silicon photovoltaic cell.

Background technique

Solar photovoltaic cells (referred to as photovoltaic cells) are used to directly convert the light energy of the sun into electrical energy. At present, silicon solar cells based on silicon are widely used in ground photovoltaic systems, which can be divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar cells. In terms of comprehensive performance such as energy conversion efficiency and service life, monocrystalline silicon and polycrystalline silicon cells are superior to amorphous silicon cells.
