Household solar battery shrapnel

The solar cell shrapnel is the main material in the solar cell module. There is a blue anti-reflection film on the surface of the solar cell and silver-white electrode grid lines. Many of the thin grid lines are the leads from the surface electrodes of the battery shrapnel to the main grid lines. The two wider silver wires are the main grid lines, also called electrode lines or upper electrodes. There are also two (or intermittent) silver-white busbars on the back of the battery shrapnel, called the bottom electrode or the back electrode. The connection between the battery shrapnel and the battery shrapnel is realized by welding the interconnection bar to the main grid. Generally, the electrode wire on the front is the negative wire of the battery shrapnel, and the electrode wire on the back is the positive wire of the battery shrapnel. Regardless of the area of u200bu200bthe solar cell shrapnel (whole piece or cut into small pieces), the peak output voltage between the positive and negative electrodes of a single piece is 0.48~0.5v. The area of u200bu200bthe cell is proportional to the output current and power generation. The larger the area, the greater the output current and power generation. Qualified solar cell shrapnel should have the following characteristics. (1) It has stable and efficient photoelectric conversion efficiency and high reliability. (2) The use of advanced diffusion technology ensures the uniformity of conversion efficiency throughout the chip. (3) Using advanced pecvd film-forming technology, a dark blue silicon nitride anti-reflection film is plated on the surface of the cell, and the color is uniform and beautiful. (4) Use high-quality silver and silver-aluminum metal pastes to make back field and grid electrodes to ensure good conductivity, reliable adhesion and good electrode solderability. (5) High-precision screen printing graphics and high flatness make the solar cell shrapnel easy for automatic welding and laser cutting.
