Use of Polysiloxane Gel as Laminate for Solar PVT Collectors

Abstract

High temperature resistant polysiloxane gel has been tested for unglazed and glazed solar PVT collector prototypes as a lamination compound. Unglazed and glazed PVT collector prototype with polysiloxane laminate have been compared with state-of-art PVT collectors (based on EVA compound) available on the market. The comparison has confirmed an excellent performance of the polysiloxane gel in terms of optical transparency and heat transfer.
