Solar cells are the most rapidly developed link in new energy currently. solar cell. Its construction and production process have been finalized, and the product has been widely used in space and ground. This solar cell is made of a high-purity silicon rod. In order to reduce production costs, solar cells such as solar cells for ground applications are now using solar-grade silicon rods, and material performance indicators have been relaxed. Some of them can also use the head and tail materials processed by the semiconductor device and the waste single crystal silicon material to be re-drawn into a silicon rod for solar cells.

Product Features

• Acid-textured surface and silicon nitride anti-reflection film can absorb most of the incident light.
• Advanced gettering process, surface passivation process and aluminum back-field treatment technology ensure the high quality of the cell.
• Advanced screen printing technology ensures that silicon wafers can produce highly accurate patterns under constant switching and interconnection
• The finished battery chip can resist the mechanical external force of a certain strength and continuously maintain the stability of electrical performance.
• All specifications battery chips are PID resistant.
