Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0012] Fig. 2 is the first embodiment of the present invention, which consists of back protective film 1, lower surface EVA film 2, battery chip series group 3, upper surface EVA film 4, light-receiving surface glass 5, and sunlight is injected from light-receiving surface glass 5 , so that the cells connected in series group 3 generate electricity. The feature of this embodiment is that a layer of ceramic thin film 6 is compounded on the back protective film 1. The ceramic thin film 6 has the characteristics of low moisture permeability and low air permeability, and protects the solar cell module against moisture and oxidation.

[0013] The ceramic film 6 is a metal or non-metal inorganic compound film, which can be any one or more of metal or non-metal inorganic compounds such as silicon oxide, titanium oxide, aluminum oxide, silicon nitride...

Abstract

The invention relates to a solar battery element with ceramic film. Wherein, the surface of inner part of organic transparent surface or back protective element is added with one layer of ceramic film. It has the advantages of waterproof and oxidization-proof abilities, with long service life.

Description

technical field [0001] The invention relates to photovoltaic power generation technology, in particular to a solar battery module. Background technique [0002] At present, an industrial standard solar cell module with crystalline silicon as the main substrate is shown in Figure 1, which consists of a back protective film 1, an EVA film 2 on the lower surface, a battery chip series group 3, an EVA film 4 on the upper surface, and a light-receiving surface. Glass 5 composition. Five layers of materials are hot-pressed into a whole solar cell module under vacuum. The battery chip series group 3 is a component for solar power generation, and the light-receiving surface glass 5 is a light-transmitting element, which can also be made by a transparent organic film. The function of the EVA film is as a bonding and sealing resin, so that these layers of materials form a whole. [0003] The known prior art is to use organic thin film as the protective element or light-transmitting...
