Description

technical field [0001] The invention relates to the fields of solar photovoltaic power generation and photocatalytic water purification. Background technique [0002] As a non-polluting, renewable new energy source, solar energy has very broad prospects for development, especially in photovoltaic power generation and photocatalytic water treatment. Photovoltaic cells are greatly affected by environmental factors such as temperature. When the temperature rises, the output voltage of photovoltaic cells will drop. Generally, for every 1°C increase in temperature, the power generation efficiency will drop by 0.4%. The normal operating temperature of ordinary solar photovoltaic panels is generally at 20-25°C, while the operating temperature of ordinary solar photovoltaic panels can reach above 70°C in summer, and above 50°C in winter, so the heat accumulation of solar photovoltaic power generation system causes the rise of operating temperature, which affects its power generation...
