Abstract
The present invention provides an encapsulation material for a solar cell and a solar cell module using the encapsulation material. The encapsulation material comprises an encapsulation material layer (2) and a non-woven fabric layer (1), wherein the non-woven fabric layer (1 ) has a gram weight of 5 to 100 g / m2 and a permeability of from 710 to 11,000 L / m2 / s. The encapsulation material of the present application can effectively avoid overflow issues relating to a conventional encapsulation material, thereby avoiding numerous undesired results. Additionally, the solar cell module of the present invention is advantageous in a number of aspects, such as, for example, greater safety, better operability and lower costs, etc. Upon aging, the encapsulation material of the present invention exhibits much better adhesive strength than that in the prior art.
Description
technical field [0001] The present invention relates to an encapsulation material for solar cells, and more particularly, to an encapsulation material without overflow problem and a solar cell module using the encapsulation material. Background technique [0002] Solar energy is an inexhaustible and efficient clean energy. Solar cells directly and efficiently harness the sun's energy, and their widespread adoption depends on their cost per watt being competitive with conventional electricity. In order to reduce the cost of power generation per watt, one method is to improve the power generation efficiency of solar cells through technological innovation, while the other method is to reduce costs, including raw material costs, manufacturing costs, etc. With the long-term development of solar cells, the manufacturing technology of solar cells has become increasingly mature. Therefore, it is difficult for solar cell technology to achieve breakthroughs in power generation effici...
