Problems solved by technology

However, as the voltage of the cells is getting higher and higher, the number of single strings that can be connected in series at the system end is getting smaller and smaller. A certain number of combiner boxes and cable configurations at the system end can only be connected in parallel due to the high voltage of the components. Components increase the cost of the system to a certain extent, which violates the original intention of reducing the LCOE of components

Abstract

The invention discloses a solar cell module and a fabrication method thereof. The solar cell module comprises a plurality of solar cell strings, wherein the plurality of solar cell strings are connected in series to form a solar cell string group, each solar cell string comprises a slicing cell piece or more than two slicing cell pieces connected in series, the slicing cell piece is formed by cutting the whole solar cell piece, each the solar cell piece is cut to form n slicing cell pieces, n is larger than or equal to 2, m solar cell strings are connected in parallel in each solar cell string group, and m is larger than n. By the solar cell module and the fabrication method, the problem of hot spot of a high-power module can be solved to a great extent, and the cost is reduced.

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] Photovoltaic power generation, as a non-polluting new energy source, is highly praised by people in today's deteriorating global environment, but so far, due to the high cost of power generation, it has still become a bottleneck for the popularization of photovoltaic power generation. Therefore, improving the power generation capacity of solar cell modules and reducing the LCOE cost of power generation are the fundamental measures to promote the popularization of photovoltaic power generation. [0003] However, in the prior art, 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 hot spot risk of high-power components, there are three main solutions, 1) reduce the number of cells protected by a unit diode; 2) reduce t...
