Novel photovoltaic assembly structure

Abstract

The invention discloses a photovoltaic assembly structure of a photovoltaic building part. The structure successively comprises a glass layer, a solar cell and a backboard from top to bottom. A backboard material is a metal sheet, glass or composite sheet material. An insulation film layer is arranged between the solar cell and the backboard. The solar cell and the insulation film layer are connected through an EVA rubber sheet. The insulation film layer and the backboard are connected through the EVA rubber sheet or an adhesion agent. The insulation film layer is a polyimide, polyethylene glycol terephthalate and polypropylene film or an organic silicon film. By using the photovoltaic assembly structure of the photovoltaic building part of the invention, an insulating property is good, a heat dissipation effect is good and production manufacturing cost is low; structure intensity of the photovoltaic assembly is increased; simultaneously, problems that bonding of the related materials is difficult, the EVA is easy to age and weather-proof performance is poor are solved; the photovoltaic assembly structure and other materials can be combined and form the photovoltaic building part and other products.

Description

technical field [0001] The invention relates to a photovoltaic component structure in a building photovoltaic component. Background technique [0002] Solar cells use the photovoltaic effect to convert solar energy into electricity, but a single cell cannot be used as a power source alone. After several solar cells are connected in series, they are electrically connected and structurally packaged to form a photovoltaic module. The photovoltaic module is the smallest and indivisible power generation device in photovoltaic power generation. After years of technology development and market inspection, the packaging process and technology of photovoltaic modules have become very mature, and the backplane mainly uses polymer materials such as TPT. However, the thermal conductivity of the TPT backsheet is low and it can spontaneously ignite. When the solar cells generate heat due to hot spots, they cannot conduct the heat out in time, and there is a fire hazard. In practical appl...

Problems solved by technology

Although the anodized layer can play an insulating role, it requires a relatively thick anodized layer, which doubles the cost of the backplane and cannot be promoted and applied in the market
