Problems solved by technology

[0005] By cutting the large-size battery into 1 / 3 pieces, the current of a single battery after slicing is 1 / 3 of the whole battery. After the above-mentioned optimized layout design, the final output current of the module is 2 / 3 of the whole battery, so as to solve the problem The problem of excessive current in large-sized batteries makes the final voltage and current of the components basically consistent with the current conventional component parameters; at the same time, the reduction of current can correspondingly reduce the occurrence of abnormal problems such as hot spots

Abstract

The invention provides a crystalline silicon cell assembly and a solar photovoltaic cell panel, the crystalline silicon cell assembly comprises at least six even number of cell strings, every two cell strings are sequentially connected in parallel and then in series, each cell string comprises a plurality of slice cells which are connected in series, the slice cell is one third of a cell slice obtained by cutting a photovoltaic cell piece.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a crystalline silicon battery assembly and a solar photovoltaic battery panel. Background technique [0002] With the development of high-efficiency batteries, the size of batteries has gradually increased. At present, large-size batteries such as 158.75, 161.75, 166, and 210mm have been gradually developed from 156mm. As the size of the battery increases, the Is short-circuit current of the battery sheet and the module continues to increase. In order to reduce the Rs (series resistance), at present, the battery is cut in half (1 / 2 piece) to produce half-chip modules. By cutting the battery in half (1 / 2 piece), Isc and Rs are reduced, but the current increases with the increase in battery size. Even after slicing, because the circuit is finally connected in parallel, the component Isc will still increase. , which ultimately affects the matching of the system installation. [...
