Solar cell panel lamination apparatus and lamination method

Abstract

The present invention provides a solar cell panel lamination apparatus and a lamination method, wherein the lamination apparatus comprises an upper chamber and a lower chamber. A first airbag is provided in the upper chamber, and a thermoconductive filler is perfused in the first airbag. The first airbag is in connection with a constant-temperature heater through a first air circulating line, an arch support is arranged in the lower chamber, an arch upper bracket, matched with with the degree of curvature of the arch support, is disposed between the upper chamber and the arch support, and the lower chamber is also provided with a vacuum extraction port. The lamination apparatus is simple in structure, has high yield, and is suitable for producing solar panels with a curved surface.

Description

【Technical field】 [0001] The invention relates to the field of photovoltaic solar cells, in particular to a solar cell panel lamination device and lamination method. 【Background technique】 [0002] Today, when the world's non-renewable energy sources are depleting day by day, the development and utilization of new energy sources is an urgent matter. As an inexhaustible clean energy source, solar energy is an alternative energy source widely used at present. It is of great significance to vigorously develop and utilize solar energy to alleviate the world energy crisis. [0003] Photovoltaic panels are the core components of solar power generation. In the current production process of high-efficiency photovoltaic panels, lamination is a very critical process. The main process is to place multi-layer solar cell components and colloids at a certain temperature and Under the vacuum state, the colloid is melted and solidified to achieve the purpose of bonding the components. In ...

Problems solved by technology

It can be seen that this type of laminating machine is powerless to the emerging demand for curved panels

[0005] In addition, the lamination of curved panels needs to face several major technical problems: first, the problem of uniform force needs to be solved, because solar silicon wafers and glass substrates are very brittle and will break if a little uneven force is applied; second, because The colloid needs to be heated to a certain temperature to make it melt and then solidify, and this process needs to be carried out in a near vacuum state, which makes uniform heating very difficult. If you learn from existing products, make the constant temperature platform into a curved surface In other words, due to the variety of surface specifications, different product models need to be made on different platforms, which will greatly increase the cost of manufacturing and purchasing laminator
