Abstract

The present invention provides a functional solar cell module backboard which includes a backboard functional layer. The inner side of the backboard functional layer is provided with a packaging functional layer. The backboard functional layer comprises a base film layer whose one side is connected with the packaging functional layer, an adhesive layer on the other side of the base film layer, and a third layer at the outboard of the adhesive layer. The functional backboard has a packaging function, and packaging process and flow of solar cell are simplified. The invention also provides a manufacturing method of the backboard, melt extrusion process can be used, the backboard functional layer and packaging layer are directly combined, and production cost is reduced.

Description

technical field [0001] The invention relates to a functional solar cell component back plate and a manufacturing method thereof. The functional backplane has a packaging function, which simplifies the production process and flow of solar cells. The functional backboard adopts the preparation method of the melting extrusion process, avoids the use of solvent-based adhesives, and reduces production costs. Background technique [0002] The current main energy source of mankind comes from fossil energy. Fossil energy refers to coal, oil, natural gas and other fuel resources that are buried underground and cannot be regenerated. Fossil fuels include coal, petroleum, oil shale, natural gas, and oil sands in order of the amount of buried energy. But in the next hundred years or so, fossil energy will be exhausted, and in the process of using fossil energy, a large amount of carbon dioxide will be emitted, which will change the gas composition of the atmosphere and cause the deter...
