Abstract
The invention discloses a solar cell interconnection structure, and the structure comprises at least two solar cell panels arranged in an imbricate structure, wherein the front surface of each solar cell panel is provided with a plurality of grid lines side by side, the front surface of each solar cell panel is also provided with a plurality of conductorsside by side, and the conductorsintersect with the grid lines and are conductively connected with the grid lines; an electrode disc is arranged on the solar cell panel located on the lower portion at the overlapping position of every two adjacent solar cell panels, the electrode discs are electrically connected with electrodes located on the back face of the solar cell panel located on the upper portion, and the electrode discs are electrically connected with the wires. According to the scheme, the internal resistance of the interconnection structure is reduced by arranging the plurality of wires, so the loss caused by the resistance of the interconnection structure can be greatly reduced. Besides, sunlight incident to the wire can be generally reflected to the surface of the solar cell panel again by adopting the wire, so the utilization rate of the light of the solar cell panel is improved, and adverse effects caused by shading of a traditional grid line electrode are reduced.
Description
technical field [0001] The present invention generally relates to the technical field of solar photovoltaic power generation, and in particular to a solar battery interconnection structure. Background technique [0002] At present, with the gradual depletion of fossil energy, solar photovoltaic cells are used more and more widely as a new energy alternative. A solar photovoltaic cell is a device that converts the sun's light energy into electricity. Solar photovoltaic cells use the principle of photovoltaics to generate carriers, and then use electrodes to extract the carriers to obtain usable electrical energy. [0003] The interconnection of solar photovoltaic cells is an important part of photovoltaic solar power generation, and its technical solutions have an important impact on the performance of photovoltaic power generation. The shingled structure is a better solution to realize the interconnection of solar photovoltaic cells. In the shingled structure, the solar p...
