Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a single-crystal single-glass TOPCon component. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of single-chip solar cells is relatively low, and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single-chip cells must be sealed into solar cell modules in series and parallel to avoid corrosion of the cell electrodes and interconnects. In addition, packaging also avoids cell breakage and facilitates outdoor installation. The quality of packaging determines the service life and reliability of solar cell modules. In order to improve the use efficiency of photovoltaic modules, a TOPCon module is required. However, when using single-crystal single-glass TOPCon modules, outdoor dust, haze, etc. will pollute the solar panels, so they often need to be cleaned. For example, a single-crystal single-glass TOPCon module proposed in the publication number "CN220190810U" relates to the technical field of photovoltaic modules, including a mounting frame and a cleaning module, wherein a TOPCon solar panel is mounted inside the mounting frame, cleaning modules are arranged on both sides of the mounting frame, and the cleaning module includes a limit frame, a servo motor, a screw rod, a receiving block, a mounting plate and a cleaning brush, a servo motor is mounted at one end of the limit frame, and a screw rod is connected to the front end of the servo motor. The single crystal single glass TOPCon module, through the arrangement of the cleaning components, can use the cleaning components on both sides of the installation frame to avoid the existing solar panels being easily polluted by outdoor dust and haze, and the high cleaning cost causing the photovoltaic module conversion efficiency to decrease when the single crystal single glass TOPCon module is used. The output shaft of the servo motor is connected to the lead screw through the coupling, and the operation of the servo motor drives the lead screw inside the limit frame to rotate;

[0003] However, in the above technical solution, although the lead screw can be driven by a motor to drive the cleaning brush to clean the surface of the solar panel through the receiving block, when multiple solar panels are laid and installed, it is often necessary to install multiple motors separately for each solar panel to drive the cleaning brush, thereby greatly increasing the use cost of each solar panel. At the same time, when the surface of the solar panel is cleaned by a cleaning brush alone, it is difficult to remove stains such as grease and bird droppings on the surface of the solar panel. Therefore, we propose a single-crystal single-glass TOPCon module to solve the above problems. Utility Model Content
