Embodiment 1
[0011] A self-cleaning solar cell anti-reflection film, with transparent materials as the base material, the base material can be selected from transparent tempered glass, PC, PS, PMMA; in this embodiment, the base material is selected from transparent tempered glass, generally speaking, the solar cell is There is no response to ultraviolet rays with a wavelength of less than 350nm and infrared rays with a wavelength greater than 1150nm, and the peak value of the response appears at 800nm~900nm. From one side to the outside, it gradually becomes a silicon dioxide film layer, a titanium dioxide film layer, and a silicon dioxide film layer;
[0012] With the wavelength of 800nm as the reference wavelength, the layer of silicon dioxide film close to the transparent tempered glass is used by the sol-gel method, the optical thickness is a quarter of the reference wavelength, and the thickness of the film layer is 137nm; although the sol-gel method is The surface of the silicon di...
