Problems solved by technology

[0003] Since the absorption of light by the packaging glass will inevitably lead to loss of light energy, the preparation of textured surface, coating of anti-reflection film and coating of down-conversion film are all effective measures to reduce light energy loss, but the suppression effect of light energy loss is still not satisfactory

Abstract

The invention discloses down-conversion photovoltaic glass and a preparation method thereof. The down-conversion photovoltaic glass comprises an ultra clear photovoltaic glass layer and a thin light-emitting film which is 80-100 nm in thickness and positioned on one surface of the ultra clear photovoltaic glass layer; the thin light-emitting film comprises the raw materials of SiO2:xEu3+ and xNa+, wherein x equals 0.002-0.2; the content of Fe2O3 in the ultra clear photovoltaic glass layer is 0.005-0.01%, and the ultra clear photovoltaic glass layer adopts an antireflective textured structure. According to the down-conversion photovoltaic glass and the preparation method thereof, provided by the invention, short wavelength lights irradiated to solar cells can be effectively absorbed by the down-conversion photovoltaic glass, long-wave lights relatively low in energy are emitted, the spectral response of visible light wave bands of solar cells is improved, and the light use efficiency and the photoelectric conversion efficiency of solar cells are further improved.

Description

technical field [0001] The invention belongs to the technical field of packaging materials for solar cell components, and relates to a down-conversion photovoltaic glass and a preparation method thereof. Background technique [0002] A single crystalline silicon cell has limited open-circuit voltage and short-circuit current under sunlight exposure. If it is to be used as a power source or a solar power station, multiple cells must be connected in parallel and in series to form a larger cell array. The battery sheet is thin and fragile, so the components connected in series and parallel by single solar cells need to be encapsulated with photovoltaic glass pools to form battery components with good mechanical properties and adaptable to various harsh environments. [0003] Since the absorption of light by the packaging glass will inevitably lead to loss of light energy, the preparation of textured surface, coating of anti-reflection film and coating of down-conversion film ar...
