Semi-slice photovoltaic module circuit and semi-slice photovoltaic module

Abstract

The invention discloses a half-slice photovoltaic component circuit, wherein the half-slice photovoltaic component circuit includes multiple sets of battery string units, each adjacent two sets of battery string units are connected in series through a first bus bar, and each set of battery string units The two ends of the two ends are respectively connected in parallel with a diode through the second bus bar. Each battery string unit includes two battery strings connected in parallel, and each battery string includes a plurality of batteries connected in series. The first battery string unit in the plurality of battery string units The first end of the battery string unit in one group is formed as the positive pole of the half-slice photovoltaic module circuit, and the tail end of the last group of battery string units in multiple groups of the battery string unit is formed as the half-slice photovoltaic module circuit the negative pole. The invention also discloses a half-slice photovoltaic module. When the half-slice photovoltaic component circuit provided by the present invention is applied to the photovoltaic component, it not only solves the hot spot effect, but also facilitates welding operation and mass 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 bu...
