Description
Technical Field
The invention relates to the technical field of solar manufacturing equipment, in particular to an electric injection device.
Background
The LID (Light Induced Degradation) phenomenon refers to a phenomenon that power of a solar cell and a photovoltaic module is attenuated when the solar cell and the photovoltaic module are illuminated by Light. The power attenuation can directly reduce the power generation amount of the photovoltaic module, and when the power attenuation exceeds a certain range, the photovoltaic module can have larger power generation amount fluctuation when a photovoltaic power station operates. In order to reduce the influence caused by the phenomenon, the photovoltaic industry adds light-decay-resistant equipment at a battery manufacturing end to perform light-decay resistance treatment on the battery so that the battery function is recovered and reaches a stable state. Researches show that the light-induced attenuation phenomenon of a crystalline silicon solar cell (especially a P-type crystalline silicon solar cell) is mainly caused by a B-O complex in a silicon wafer, and hydrogen atoms have a good passivation effect on the B-O complex, so that at present, an electric injection device is usually adopted to inject carriers into the cell to realize hydrogen passivation, thereby reducing the influence caused by the light-induced attenuation phenomenon.
The existing electric injection equipment comprises a plurality of process cavities which are sequentially connected in series, wherein the process cavities are sequentially divided into a process cavity for heating, a process cavity for maintaining the electric injection temperature stable and a process cavity for cooling the battery piece, and the process cavity at each stage is provided with a plurality of process cavities. The charging box loaded with the battery piece enters the process cavity from the feeding port arranged at the first process cavity, and then the charging box can complete a complete electric injection process only by sequentially passing through each process cavity, so that the problem of discontinuous battery piece injection exists. And because the upper electrode and the lower electrode are required to mechanically press the battery piece when the battery piece runs to each process cavity, the battery piece may be cracked and broken due to multiple pressing operations, and the yield of the battery piece is reduced. Moreover, the battery piece needs to move among the plurality of cavities, and the temperatures among the cavities are inconsistent, so that the temperature on the surface of the battery piece is unstable, and the electric injection effect is reduced. In addition, since the cavities are arranged in series, when a problem occurs in one of the cavities, the whole electrical injection equipment needs to be shut down for maintenance, so that the electrical injection efficiency is reduced, and the productivity is reduced.
In summary, how to realize continuous injection of the battery pieces, improve the yield of the battery pieces, improve the electrical injection effect, and improve the efficiency and the productivity of the electrical injection is a technical problem to be solved urgently by those skilled in the art.
