Embodiment

[0027] See attached figure 1 and figure 2 , solar cell upper and lower electrode interconnection sheet welding and upper and lower surface cover sheet bonding to form a solar cell with cover sheet separately, bypass diode positive and negative electrode welding and single-sided glass cover sheet to make a bypass diode with cover sheet separately, and finally Then paste the two together and realize electrical connection.

[0028] 1. Fabrication of solar cells with cover sheet

[0029] Taking a solar cell with a conventional structure as an example, the side with grid lines is called the front of the solar cell, the main grid on one side is called the upper electrode, and the other side is called the back of the solar cell. Generally, the entire surface is vapor-deposited with metal electrodes, called the lower electrode. electrode.

[0030] Welding of upper and lower electrodes: Take 1 piece of large-area solar cell, 1 piece of upper and lower electrode interconnection piec...

Abstract

The invention discloses a solar battery module for a taut-string-type semi-rigid plate, and relates the technology field of solar batter arrays. The solar battery module is characterized in that the module comprises at least a solar battery, and the back surface is adhesively connected to the lower surface of a first glass cover sheet by a first cover-sheet adhesive; the front surface of the solar battery is adhesively connected to the upper surface of a second glass cover sheet by a second cover-sheet adhesive; the upper surface of the first glass cover sheet adhesively connected to a bypass diode by a bypass diode adhesive, and the bypass diode is adhesively connected to a third glass cover sheet by a third glass cover sheet adhesive; a positive electrode and a negative electrode are successively connected with the bypass diode respectively by a solar battery interconnection sheet and a bypass diode interconnection strip. According to the solar battery module, highly reliable solar battery module technology is adopted, wherein the large-size single-sheet solar battery independently forms a module, and the bypass diode is installed on the cover sheet of the back surface of the battery in a penetrated mode. The solar battery module solves the problems that traditional solar battery module manufacture is complex in process and higher in cost, and obviously improves the reliability of products.

Description

technical field [0001] The invention relates to the technical field of solar battery arrays, in particular to a solar battery module for string-type semi-rigid panels. Background technique [0002] The existing solar cell module is composed of several small-sized solar cells spliced ​​in series and parallel by interconnecting sheets. A bypass diode is installed at the missing corner of each small-sized solar cell, and glass cover sheets are pasted on the upper and lower surfaces of the solar cell. It is sealed together with the bypass diode between two layers of cover sheets. [0003] The manufacturing process of solar cell modules in the prior art is complicated; multiple spliced ​​cells need to be matched, multiple interconnected sheets and multiple bypass diodes are used, and any damage to any battery or bypass diode in the module will result in the replacement of the entire module. The cost is high; the bypass diode is installed at the missing corner, and there is a sli...
