1. Background:
CIGS photovoltaic panels are mainly composed of Cu (copper), In (indium), Ga (gallium), and Se (selenium), which have strong light absorption ability, good power generation stability, high conversion efficiency, and good weak light effect. Therefore, they have long daytime power generation time, high power generation capacity, low cost, and short cycle. Compared to existing crystalline silicon photovoltaic panels, there has been a significant improvement in cost, efficiency, and power generation. However, in hot weather conditions, the temperature of CIGS photovoltaic panel solar street lights will immediately increase, leading to a decrease in battery efficiency and lifespan. And the current is unstable, which can easily cause damage to LED light sources.

This utility model provides a CIGS photovoltaic mechanism for solar street lamps; Including CIGS photovoltaic panels, installation frames, sleeves, and power modules. CIGS photovoltaic panels are fixed above the installation frame, and sleeves are fixed on the lower side of the installation frame; The inner wall of the power supply box of the power component is covered with an insulation layer, and the battery is arranged inside the power supply box. There are air inlet and air outlet on both sides of the power supply box. Two fans are installed at the air inlet and air outlet, and temperature sensors are installed inside the power supply box. Semiconductor refrigeration chips extend into the internal cavity of the power supply box. The power component detects the temperature of the power box battery through a built-in temperature sensor. When the temperature drops below the normal operating temperature, it controls the semiconductor cooling chip to generate heat to provide the temperature of the battery; When the temperature rises, the excess heat can be discharged through a reserved ventilation port through a fan, or cooled by a semiconductor cooling chip. The power component automatically adjusts the temperature of the battery to maintain it at a suitable temperature.
