بررسي اثر نانو لايه هاي نقره كندوپاشي در بازتابش انرژي حرارتي نور خورشيد توسط شيشه سفيد در آينه هاي حرارتي- خورشيدي

Study the sputtering Nano-Silver effect on reflected the sun heating energy by white glass in solar heating mirror

In this resead solar mirrors were made from silver nano layers on a white glass substrate. In this regard the DC magnetron sputtering was used for diposition of silver. ITO layers were used to enhance the adhesion of the main layer . The layers were characterized by spectrophotometer, RBS and XRD. It was observed that IR reflection was enhanced with the increase in Ag thickness. However increase in ITO layer and substrate temperature , and decrease in grain size, decreased the IR reflection.
