Solar radiation wavelength range of about 0.15-4 microns, can be divided into ultraviolet, infrared region, and visible light, solar energy radiation is mainly in the 0.16-2.0 microns, old-fashioned vacuum tube directly absorption of solar radiation in the wavelength range 0.2-0.5 microns, Zijin frequency vacuum tube technology with increased frequency conversion layer can be greater than 0.5 micron wavelength of light wavelength frequency adjustment, transformation absorption, increase the absorption rate and improve the collection efficiency and more effective absorption of solar radiation energy of the light, so that the endothermic effect is better, get the heat higher...
