Description

Technical Field

[0002] Photovoltaic cells, also known as solar cells or photovoltaic cells, are semiconductor devices that can directly convert sunlight into electrical energy. Photovoltaic cells are usually composed of multiple photovoltaic cells, and their main function is to absorb solar photons and convert them into electron flow, thereby generating voltage and current. Photovoltaic cells are the core components of solar photovoltaic systems and are widely used in solar power generation, solar photovoltaic panels, solar cell groups and other fields. Photovoltaic cell testing can help ensure that the quality of cells in the production process meets standards and specifications. By testing key parameters such as cell size, thickness, surface flatness, electrical properties, etc., defects or defective products in the manufacturing process can be discovered in time, and corresponding measures can be taken to ensure that product quality meets requirements.

[0003] Most of the existing fixing devices for testing photovoltaic cells use top blocks to clamp the two sides or four sides of the cell. Since the edges of the cell are relatively thin, the edges of the cell are clamped for a long time during the clamping process, causing the edges of the cell to bend, thereby causing the cell to be damaged during testing.

[0004] In view of this, we propose a photovoltaic cell detection fixture. Utility Model Content
