Abstract

The invention relates to a solar cell photovoltaic module and a solar cell photovoltaic assembly. The provided solar cell photovoltaic module comprises battery pieces arranged in matrix and solder strips which connect the battery pieces arranged in matrix in series. Main gates are distributed on the light-receiving surfaces of the battery pieces. The main gates comprise row main gates and column main gates perpendicularly intersecting the row main gates. Pads at the intersections of the row main gates and the column main gates are distributed on the light-receiving surfaces of the battery pieces. Back electrodes corresponding to the pads one to one are distributed on the backlight surfaces of the battery pieces. The solder strips comprise series solder strips and interconnecting solder strips. The series solder strips connect the battery pieces in series along the column main gates into a battery string. The interconnecting solder strips connect the battery pieces on both ends of the battery string in series along the row main gates. According to the photovoltaic module, the interconnecting solder strips connect the battery pieces on both ends of the battery string in series alongthe row main gates, eliminating interconnection strips on both ends of the battery string, reducing the area occupied by the photovoltaic module, reducing the overall material cost, reducing the internal impedance, and reducing the power loss.

Description

Technical field [0001] The present invention relates to the technical field of solar cells, and more specifically to solar cell photovoltaic modules and solar cell photovoltaic modules. Background technique [0002] As a kind of green new energy, solar energy has many advantages such as inexhaustible, clean and environmental protection. At present, one of the main ways to use solar energy is to convert light energy into electrical energy through photovoltaic cell modules. Traditional photovoltaic cell modules have several photovoltaic cells connected in series and packaged in a square array to form a large-area photovoltaic power station. Among them, the photovoltaic cell absorbs light energy, and the accumulation of different signs of charge appears at both ends of the cell, which generates "photovoltaic voltage", that is, the "photovoltaic effect". Under the action of the photovoltaic effect, electromotive force is generated at both ends of the solar cell. , Thereby converting...
