Abstract

The invention provides a solar cell. The solar cell comprises multiple cutting areas. Each cutting area comprises multiple generating units (10), a front surface electrode (30) which is disposed at the front surface of the multiple generating units (10) and is connected with the front surface of each generating unit (10) in the cutting area, and a back surface electrode (40) which is disposed at the back surface of the multiple generating units (10) and is connected with the back surface of each generating unit (10) in the cutting area. The technical scheme provided by the invention effectively solves the problem that the solar cell is inconvenient to cut for use after manufacturing molding in the prior art.

Description

technical field [0001] The present invention relates to the technical field of solar energy, in particular to a solar cell. Background technique [0002] At present, the solar cell modules produced at home and abroad are all composed of many power generation units in one solar cell. The power generation capacity of each power generation unit is relatively small and cannot be used alone, so it is necessary to collect the power generated by the power generation units. Each power generation unit has a positive pole and a negative pole. The positive poles or negative poles connected to each row of power generation units are first connected through the auxiliary grid line, and then the electricity collected on all the auxiliary grid lines is collected through the main grid line. [0003] In this way, the solar battery module can be used by connecting the main grid line to the electrical appliance or the storage battery, and the aggregation of the electricity generated by the pow...
