Abstract

The invention discloses a solar battery with a macromolecular multilayer film and a manufacturing method thereof. The solar battery comprises the solar battery and the macromolecular multilayer film, wherein the macromolecular multilayer film is arranged on the solar battery and is provided with at least two macromolecular optical interference layers with two different refractive indexes; therefore the macromolecular multilayer film can reflect sunshine waveband which is not suitable to be absorbed by the solar battery, and allows the suitable sunshine wave band to pass; the solar battery only absorbs the sunshine wave band which are suitable for energy gap thereof, and the reflected sunlight or the light which is not absorbed by the solar battery also can be used for a subsequent illumination system, a power generation system, and a heating system. Therefore, the solar battery is prevented from generating excess heat to raise temperature, can reduce the heat dissipation load of a cooling system, and effectively maintain the photoelectric conversion efficiency of the solar battery.

Description

technical field

[0001] The invention relates to a solar cell with a polymer multilayer film and its manufacturing method, in particular to a solar cell that can reflect light bands that are not suitable for solar cells to absorb and utilize, and reduce the heat dissipation burden of the heat dissipation system, thereby maintaining high photoelectric conversion efficient solar cells. Background technique

[0002] By the way, energy generally refers to the energies that can be used by human beings, such as petroleum, light, heat and nuclear energy, among which petroleum is the most important form of energy in modern society. Petroleum has been the driving force for all human economic activities in the past century. The exploitation of crude oil is gradually becoming scarce, and when the demand for oil in countries around the world remains high, various urgent phenomena derived from oil are heard from time to time. All economics, politics, and even wars are closely related to o...
