Abstract

The invention provides a device for testing the electrical properties of a solar battery. The device comprises an upper test bench and a lower test bench. The upper test bench includes a copper wire group for testing the current and voltage on the front face of a battery piece, a retractable spring for adjusting the tension of the copper wires, a bus copper wire connected to all the current and voltage copper wires, a main frame, and a lifting device connected to a motor. The lower test bench includes a substrate, a copper conductive bar, a bus copper wire connected to all the current and voltage copper conductive bars, and adsorption holes. The device can avoid the virtual high test short-circuit current caused by the reflection of a tabletop, and also solve the conductive contact betweenthe front and back electrodes of a double-sided battery. Integrated with an automatic transmission device, the device solves the feasibility of testing the electrical properties of such batteries inmass production.

Description

technical field [0001] The invention relates to a test device for the electrical performance of a solar battery, which belongs to the field of solar batteries. Background technique [0002] A solar cell is a device that converts light energy into electrical energy by using the photovoltaic effect. At present, the substrate of the mainstream commercial battery is crystalline silicon material, and the advanced PERC process is adopted on the P-type silicon crystal. Generally, this kind of battery has a single-sided structure, and the main grid is the mainstream 3-5 grid. If the P-type PERC battery is to be made into a double-sided structure, the traditional busbars will be canceled at the same time for the front electrode and the back electrode, and it will be designed as no busbar or multiple thin busbars. With such a structure, conductive contacts are formed only on the fine grids. Then the busbar-pressed probe row structure of the traditional solar cell electrical performa...
