Abstract

The invention belongs to the technical field of solar cell modules, and particularly relates to a double-glass imbricated photovoltaic module. The double-glass imbricated photovoltaic module comprisesa battery array, first glass arranged above the battery array and second glass arranged below the battery array. The battery array comprises at least two sets of battery strings formed by connectingat least two battery pieces in series, an insulating adhesive tape and grid lines, wherein the battery strings are arranged side by side on the same plane, and the side surfaces of the battery stringsare close and are not contacted; the insulating adhesive tape covers the contact parts of the adjacent battery strings, and the contact parts of the adjacent battery strings are bonded with each other; and the grid lines are arranged on the upper surface or / and the lower surface of the battery piece. The invention provides the double-glass imbricated photovoltaic module which can significantly enhance the stability and reliability of battery interconnection in the module on the premise of ensuring that a light receiving area of the back surface of the battery is not influenced basically.

Description

technical field [0001] The invention belongs to the technical field of solar cell components, in particular to a double-glass shingled photovoltaic component. Background technique [0002] A photovoltaic module is a unit with rated voltage and current output formed by packaging multiple solar cells, and is the smallest power generation unit that can be used independently in a photovoltaic power generation system. In traditional photovoltaic modules, the cells are connected by ribbons and there is a certain gap between adjacent cells. The use of a large number of ribbons increases the internal loss of the module, and the existence of more gaps reduces the space utilization of the module. rate, resulting in a lower output per unit area. [0003] In recent years, high-power components have become more and more popular in the market. The development of high-efficiency battery technologies such as PERC, IBC, and HIT has greatly improved the efficiency of photovoltaic modules. ...
