Research on Reliability of Packaging Materials for PVT Modules

Abstract

This paper studies the difference in heat transfer and adhesion performance of glass fiber substrate thermal conductive double-sided adhesive, PVC substrate double-sided adhesive, and PET substrate double-sided adhesive to thermal conductive materials and polymer materials in photovoltaic and thermal integrated modules. Studies have shown that the use of glass fiber-based thermally conductive double-sided adhesive to bond polymer materials and thermally conductive materials can achieve the normal use of PVT modules under weather-resistant conditions. Research has shown that glass fiber-based thermally conductive double-sided adhesive has better adhesion than other materials., Initial viscosity, static shear force, thermal conductivity, etc., can realize the normal use of PVT modules under weathering conditions.
