YogiSun vacuum tubes introduce the latest trivalent element technology which includes high borosilicate glass and ALN/AIN-SS/CU selective complex absorptive coating. This invention increases the performance, absorption and gives a low reflection ratio. Through the interlayer as shown in the diagram, the vacuum has a unique effect of thermo, withstanding temperatures up to 380 C, hence performing a strong heating ability with an absorption rate of 96%. This technology is into effect by various countries such as Germany, China, UK and USA over various solar projects.
