Abstract

The invention provides a photovoltaic cell, comprising a photovoltaic conversion module which is used for absorbing light energy and converting the light energy to electrical energy. The photovoltaic conversion module is provided with a light incident plane, wherein the light incident plane is provided with a glass layer doped with europium element. The europium element doped in the glass layer is existed in the form of europium oxide, which allows the incident light with the wavelength of 350 to 470 nm can be translated to the emergent light with the wavelength of 570 to 720 nm. The micro-structure of the glass layer comprises at least two splitphases; a phase interface is formed between different splitphases, and the phase size of each splitphase is less than 500 nm; and the phase interface is used for refracting or reflecting incident light to the europium element to improve the photo transformation efficiency of the photovoltaic cell.

Description

technical field [0001] The invention relates to the technical field of photoelectric conversion, in particular to a photovoltaic cell. Background technique [0002] Solar cells use renewable and environmentally friendly energy solar energy to generate electricity, that is, the sun's radiation energy is converted into electrical energy through semiconductor materials (see "Grown junction GaAs solar cell", Shen, C.C.; Pearson, G.L.; Proceedings of the IEEE, Volume 64 , Issue 3, March 1976 Page(s): 384-385). The structure of a solar panel mainly includes a photoelectric conversion layer. The photoelectric conversion layer is composed of a PN junction formed by a P-type semiconductor material and an N-type semiconductor material. When sunlight irradiates on the semiconductor material of the photoelectric conversion layer, the photoelectric conversion layer absorbs the light in the sunlight corresponding to the wavelength band of the semiconductor material. The photons in the ...
