[0002] Photovoltaic lighting devices generally use conventional bifacial PERK cells, and the efficiency of converting absorbed light into electricity is generally between 22% and 23%. The efficiency of the HJT cells used in this device is 24% to 25%, and its low-light effect is better (under 600W / ㎡ radiation intensity in the evening or on cloudy days), which is about 0.5% to 1% higher than that of conventional bifacial PERK cells. The attenuation rate of HJT cells is lower than that of conventional bifacial PERK cells, and the life cycle is longer. In addition, the temperature coefficient is lower, which produces a higher open-circuit voltage, ensuring higher output power and weather resistance durability.

[0018] Figure 1 The cross-sectional structure of the curb photovoltaic induction lighting device is schematically shown; Figure 2 The main structure of the curb photovoltaic induction lighting device is schematically shown.
[0019] like Figure 1 As shown, a curb photovoltaic induction lighting device is arranged based on the curb structure, including a mounting shell 5 and a solar laminate arranged in the mounting shell 5, the mounting shell 5 is fixedly arranged on the curb structure, and a rubber pad 12 is sandwiched between the mounting shell 5 and the curb structure to ensure that the contact portion between the mounting shell 5 and the curb has a certain buffer and adapts to the surface structure of the curb.
[0020] like Figure 2 As shown, the aforementioned solar laminate comprises a HJT cell sheet 1, which is a plurality of HJT cell sheets 1, which are combined into one piece in a stacked manner, and the aforementioned HJT cell sheets 1 are combined into an HJT cell unit by an EPE adhesive film 3. A lighting unit is fixedly arranged in the mounting housing 5, and a control unit is arranged in the lighting unit, and the lighting unit is powered by the aforementioned HJT cell unit.

It is worth noting that the aforementioned lithium battery 10 is powered by an HJT battery unit. The HJT battery unit and the lithium battery 10 are connected via a busbar 6. The HJT battery unit absorbs light energy and converts it into electrical energy, and supplies the electrical energy to the lithium battery 10 via the busbar 6, and the lithium battery 10 stores the electrical energy.
