Abstract

The invention discloses a solar cell module and a manufacturing method. The solar cell module comprises multiple solar cell strings; multiple solar cell strings are parallelly connected to form a solar cell string group; each solar cell string comprises a cell slice or more than two serially-connected cell slices; the cell slice is cut from a whole solar cell, each solar cell can be cut into n cell slices, n is larger than 2, and the cutting direction of each solar cell is a transverse direction or an oblique direction; and m solar cell strings are parallelly connected in each solar cell string group, m is smaller than n, and m is no smaller than 2. According to the solar cell module and the manufacturing method of the invention, the output power can be effectively improved, a problem of a hot spot on a high-power module can be solved to a certain degree, electrical loss of a cable at a system end can be reduced and the power generation ability of the module can be improved.

Description

technical field [0001] The invention relates to the technical field of solar components, in particular to a solar cell component and a manufacturing method. Background technique [0002] With the rapid development of solar cell and module technology, high-power modules have become the trend of the future. However, there is a risk of hot spots in high-power components, and the higher the power, the greater the risk. In order to reduce the risk of module hot spots, there are three commonly used methods: 1) reduce the number of cells protected by a unit diode; 2) reduce the working current and power of a unit string of cells; 3) control the leakage current of the battery. Among them, reducing the number of cells protected by a unit diode requires increasing the number of diodes, changing the connection method of the components, and one pole of the bus bar needs to be extended and passed through the back of the battery string to connect the diode between the other pole, thus in...
