However, the materials of the solar cell back plate in the prior art have the problems of poor heat dissipation effect, poor conductivity and the like. When the temperature is too high, the heat dispersion performance of the solar cell backboard is poor, the temperature of the solar cell backboard cannot be reduced quickly and effectively, the electronic thermal motion is aggravated due to high temperature, the power generation internal resistance of the solar cell board is increased, the power generation output power is reduced, the energy conversion efficiency is reduced, the aging of materials can be accelerated due to long-time high temperature, and the service life of the photovoltaic cell is further shortened.
