Problems solved by technology

[0002] At present, most of the photovoltaic modules use the whole cell welding string assembly, and its power and module conversion efficiency are limited. In order to improve the power and conversion efficiency, the half-slice technology welding string assembly is used. Although the conversion efficiency is improved, there will be problems. Hot spot effect, although some products can be improved by improving the hot spot effect, but due to the great limitations in the production process, it is difficult to produce in batches, or the labor cost is too high during production, or the equipment transformation is too expensive, etc. question

Abstract

The invention discloses a semi-slice photovoltaic module circuit. The semi-slice photovoltaic module circuit comprises multiple sets of cell string units. Every two adjacent sets of cell string units are connected in series through a first busbar, and the two ends of each set of cell string unit are connected in parallel with one diode through a second busbar. Each set of cell string unit comprises two parallel connected cell strings. Each cell string comprises multiple series connected cells. The head end of the first set of cell string unit of multiple sets of cell string units forms the positive electrode of the semi-slice photovoltaic module circuit. The tail end of the last set of the cell string unit of multiple sets of cell string units forms the negative electrode of the semi-slice photovoltaic module circuit. The invention also discloses a semi-slice photovoltaic module. When the semi-slice photovoltaic module circuit is applied to the photovoltaic module, the hot spot effect can be solved, and welding operation is enabled to be convenient so as to be convenient for batch production.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a half-slice photovoltaic component circuit and a half-slice photovoltaic component including the half-slice photovoltaic component circuit. Background technique [0002] At present, most of the photovoltaic modules use the whole cell to weld the string assembly, and the power and module conversion efficiency are limited. In order to improve the power and conversion efficiency, the half-slice technology is used to weld the string. Although the conversion efficiency is improved, there will be problems. Hot spot effect, although some products can be improved by improving the hot spot effect, but due to the great limitations in the production process, it is difficult to produce in batches, or the labor cost is too high during production, or the equipment transformation is too expensive, etc. question. [0003] Therefore, how to not only solve the problem of hot spot effect but ...
