Problems solved by technology
However, due to the difficulty in processing the pyramid-shaped secondary optical lens, it is expensive, making the cost of concentrated photovoltaic modules very high
The existing technology gradually adopts spherical secondary optical elements to replace pyramidal optical lenses, because spherical optical elements can be mass-produced quickly by ball milling process, so the price is cheap, and spherical secondary optical elements are made of flat ceramic base double Surface copper clad board cannot be fixed effectively

The invention discloses a packaging structure suitable for high-power concentrating solar cells, which includes a positive electrode conductive base, an insulating spacer ring, a negative electrode conductive ring, and a secondary optical lens support structure that are sequentially socketed from the inside to the outside. The positive electrode is connected to the positive electrode conductive base, the negative electrode on the front of the solar cell is connected to the negative electrode conductive ring through a wire, the positive electrode conductive base and the negative electrode conductive ring are separated by an insulating spacer ring, and the secondary optical element is arranged above the solar cell and passed through The supporting structure of the secondary optical lens is positioned and supported, and the center of the secondary optical element is aligned with the center of the solar cell. The positive electrode conductive base of the present invention can quickly conduct the heat generated by the solar cell to the electric base plate, thereby effectively avoiding the damage to the solar efficiency caused by heat accumulation, and the positive and negative electrodes of the solar cell packaged by the present invention are all on the same surface, It is convenient to directly use the SMT chip technology for automatic mounting, which improves the production efficiency.
Description
technical field [0001] The invention belongs to the technical field of solar energy utilization, and particularly relates to a packaging structure suitable for high-power concentrating solar cells. Background technique [0002] Solar energy has excellent characteristics such as cleanness, no geographical limitation of resources, and inexhaustibility for human beings. It is more and more popular among people. Among them, the technology of solar photovoltaic utilization, that is, the direct conversion of sunlight into electrical energy through photovoltaic devices, is particularly eye-catching. However, due to the high price of photovoltaic cells in photovoltaic systems, the cost of photovoltaic power generation at this stage is several times higher than that of conventional power generation. Therefore, photovoltaic technology has not ushered in the era of large-scale application. [0003] Under the current circumstances, one of the effective ways to reduce the cost of photovo...
