CN2577445Y - Solar cell assembly - Google Patents

Abstract

A solar cell assembly, which is characterized in that a plurality of solar cells are assembled into a solar cell assembly with the following packaging structure, that is: the solar cells are arranged in a transparent groove frame, and the solar cells face the transparent groove At the bottom of the frame, the solar cells are encapsulated in the groove frame with a transparent adhesive. This structure can not only effectively protect the solar cell chip, so that it has anti-pollution, anti-mechanical damage, anti-humidity and other properties, but also can ensure sufficient light transmittance to maintain the efficiency of the cell, thereby greatly improving its service life.

Description

A solar cell module

technical field

The utility model relates to a packaging structure of a solar cell assembly.

Background technique

The current method of encapsulating solar cell modules is mainly to use liquid adhesive for casting or EVA resin for lamination and encapsulation. And most of them are in the form of adhesive/battery sheet/lower bottom plate. The battery surface is mainly covered with epoxy resin adhesive. Due to aging performance, these adhesives will generally turn yellow in about two years. The light transmittance decreased significantly. This type of packaged solar cell module also has problems such as poor mechanical protection performance, pollution prevention and moisture resistance, and its service life is greatly affected.

Contents of the invention

The purpose of this utility model is to design a solar cell assembly with a new packaging structure, so that it has better performance in terms of mechanical strength and adapting to environmental influences, so as to greatly improve the service life of the solar cell assembly.

The technical solution of the utility model is to assemble a plurality of solar cells into a solar cell module with the following packaging structure, that is, the solar cells are arranged in a transparent groove frame, and the solar cell face faces the transparent groove frame At the bottom, the solar cells are encapsulated in the groove frame with a transparent adhesive.

Said recessed frame can be made of plexiglass, polycarbonate or other clear plastics.

Said transparent adhesive can be silicone resin or modified epoxy resin.

The solar cell module adopting this encapsulation structure, its solar cell surface is covered with a transparent groove frame made of plexiglass and other materials with greater mechanical strength and adaptability to environmental protection, and the back of the frame is covered with a transparent adhesive, so that even if the sun The battery chip is effectively protected, so that it has anti-pollution, anti-mechanical damage, anti-humidity and other properties, and can ensure sufficient light transmittance to maintain the efficiency of the battery, thereby greatly improving its service life. The utility model also has the advantages of convenient manufacture and low cost.

Detailed ways

Embodiment one

As shown in Figures 1 and 2, the solar cells 1 are arranged in a grooved frame 2 of plexiglass, the solar cells face the bottom of the grooved frame, and the solar cells are encapsulated in the grooved frame with silicone rubber 3 . The specific manufacturing method can be to arrange the solar cells 1 in the grooved frame 2 of the plexiglass, and then pour the silicone rubber, heat and cure, that is to realize the encapsulation of the solar cell module.

Embodiment two

The structure of this embodiment is basically the same as that of Embodiment 1, except that the material of the groove frame is transparent polycarbonate.

Claims (3)

1. solar module that assembles by the polylith solar cell piece, it is characterized in that: solar cell piece (1) is emitted in the transparent fillister skeleton (2), its solar cell face is encapsulated in solar cell piece in this fillister skeleton with translucent adhesive towards transparent fillister skeleton bottom.

2. solar module according to claim 1, the material that it is characterized in that said fillister skeleton (2) is polymethyl methacrylate or transparent plastic.

3. solar module according to claim 1 is characterized in that said translucent adhesive is the epoxy resin of organic silicon rubber or modification.
