Study on Influence of Tin Plating Layer of Solder Strip on Electrical Properties of Photovoltaic Modules

With the continuous development of social economy, the cost reduction and efficiency increase of enterprises are very important for the development of enterprises. Starting from the packaging materials of photovoltaic modules, this paper mainly studies the influence of welding ribbon with different tin layer thicknesses on the performance of photovoltaic modules, and compares the resistivity of welding ribbon with different thickness of tin layers. The experimental results show that with the reduction of the thickness of the tin-plated layer on the non-soldering surface of the welding ribbon, the resistivity of the welding ribbon decreases, and the output power of the photovoltaic module is effectively improved.
