Abstract

The invention provides a solar cell module. The solar cell module comprises cell modules, a frame which is used for packaging the cell modules and disposed on the peripheral edges of the cell modules, a positive junction box and a negative junction box, wherein every cell module comprises a back board layer, an adhesive layer, a cell array, another adhesive layer and a glass board which are sequentially arranged. The cell array is composed of a plurality of solar cell pieces in series and / or in parallel and electrically connected with a positive leading-out end and a negative leading-out end which extend out from the cell module at different, the positive leading end is used for leading out positive currents and electrically connected with the positive junction box, and the negative leading end is used for leading out negative currents and electrically connected with the negative junction box. Therefore, the lengths of the positive leading-out end and the negative leading-out end can be shortened to a large extent to reduce the internal resistance of the solar cell module. Meanwhile, the assembling of the cell modules shortens the length of cables on the junction boxes to a large extent, reduces the resistance and the stability of the connection and is more convenient. The structural design of the solar cell module can shorten the length of cables from 1000mm to 220mm.

Description

technical field [0001] The invention relates to the field of solar cell modules. Background technique [0002] In the existing solar power generation system, multiple cells are connected in series and parallel to obtain a suitable voltage value and current value to form a solar cell array, and the backplane layer, adhesive layer, battery array, adhesive layer and glass plate are arranged in sequence After lamination, the solar cell module is formed, and the frame seal is set on the periphery, the positive and negative terminals 1 and 2 are connected to the left and right or upper and lower edges of the solar cell module to draw positive and negative currents, and the diode terminal is connected in the middle of the solar cell module 3 Connect the bypass diode, the positive and negative terminals 1, 2, and the diode terminal 3 are drawn from the middle of the edge of the backplane layer of the solar cell module, and the positive and negative terminals 1 and 2 are also connect...
