Full-series-parallel photovoltaic module and manufacturing method thereof

Abstract

The invention discloses a full-series-parallel photovoltaic assembly and a manufacturing method thereof. The full-series-parallel photovoltaic assembly comprises multiple rows of first cell groups and multiple rows of second cell groups, multiple rows of first cell groups and multiple rows of second cells The cell groups are staggered in the column direction, the first cell group includes N first cells distributed at intervals in the row direction, the second cell group includes N second cells distributed at intervals in the row direction, and the first cell in each row is the first cell group. The cell group and any adjacent row of second cell groups are arranged in a staggered arrangement, so that any two adjacent first cell groups in each row of the first cell group and any adjacent second cell group A second cell in the sheet is laminated and connected. The full-series-parallel photovoltaic module provided by the present invention has the advantages of strong anti-shading capability, small power loss when shaded, and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation component equipment, in particular to a full-series-parallel photovoltaic component and a manufacturing method thereof. Background technique [0002] The internal cells of the photovoltaic module are usually connected in series first, and then the series-connected cells are connected in series and parallel through the bus bar, and a diode is connected in parallel at the same time. When the front side of one or more cells in a cell string is blocked, the diode will be turned on due to the change in output characteristics of the cell, which will short-circuit the two strings of cells in parallel to ensure the safe operation of photovoltaic modules. . However, the photovoltaic modules in the related art still have the disadvantages of poor shielding resistance, large power loss when shielded, poor crack resistance and high manufacturing cost. SUMMARY OF THE INVENTION [0003] The pres...
