Description
Technical field
The invention belongs to that to be used for silicon be fields such as packaging glass of solar cell, be specifically related to a kind of coated glass that on glass substrate, has antireflective visible light and the difunctional composite film of reflection near infrared ray simultaneously and preparation method thereof.
Background technology
Along with human society carbon emission amount increases and conventional energy resources exhaustion day by day day by day, greatly developing cleaning new energy has become the only way that the social sustainable development and the civilization of marching toward are realized in countries in the world.Photovoltaic is one of clean energy, has obtained using widely.Silicon is solar cell at present, comprises monocrystaline silicon solar cell, polysilicon solar cell and non-crystalline silicon/microcrystalline silicon film battery, has obtained using on a large scale.The crystalline silicon band gap is about 1.12eV, and corresponding 1087nm wavelength that is to say, can produce photovoltaic effect less than the solar spectrum of 1087nm, and its optimal response wavelength is in 800～900nm scope; The band gap of non-crystalline silicon is about 1.7eV, and corresponding 730nm wavelength can produce photovoltaic effect less than the solar spectrum of 730nm, and its optimal response wavelength is in 450 ~ 650nm scope.The solar radiation spectral band scope that observes on the ground is approximately 295～2500nm, is shorter than 295nm and greater than the solar radiation of 2500nm wavelength, the strong absorption because of ozone, aqueous vapor and other atmospheric molecules in the earth atmosphere can not arrive ground.The solar spectral that arrives ground mainly contains three parts to be formed, its middle-ultraviolet lamp accounts for about 3%, visible light account for about 42% and infrared rays account for about 55%.Visible light adds up to about 45% spectrum generation photovoltaic response with ultraviolet ray, and 55% near infrared ray makes the heating of battery sheet, heats up.Crystal silicon is that the temperature power coefficient of solar cell is :-(0.35～0.50) %/℃; 1 ℃ of the every rising of temperature, output rating descends 0.35～0.50%, and the temperature power coefficient of amorphous silicon membrane battery is :-0.20%/℃; 1 ℃ of the every rising of temperature, output rating descends 0.20%.Therefore, be in the solar module at silicon, need avoid or slow down silicon chip or silicon film temperature and rise, this just needs to stop or reduces infrared transmission in the sunlight on silicon cell or thin film silicon.
