The solar photovoltaic and thermoelectric cogeneration component based on the micro heat pipe array successfully solves the technical bottlenecks of low power generation efficiency and short service life of a battery caused by high temperature of a battery back plate of the traditional photovoltaic battery, and greatly improves the solar utilization efficiency of the photovoltaic component. The medium in the isolated heat exchanger can adopt natural convection water cooling and forced circulation water cooling modes, the temperature of the battery can be effectively reduced, the temperature of the battery is controlled within 45 ℃, the battery is prevented from being overheated and hot spots, and the service life of the battery panel is prolonged; the power generation power and the power generation efficiency of the battery component are improved by 10% -30%; the waste heat utilization of the solar panel is about 50-60%, and the comprehensive utilization efficiency of the solar energy is greatly improved.
