Silicone Materials for Sustainable Energy: Emphasis on Photovoltaic Materials for Module Assembly and Installation
(Seminar/Conference)
Ann Norris, Dow Corning Corporation
The Photovoltaic (PV) industry has aggressive goals to decrease $/kWh and lower the overall cost of ownership; these goals are critical for the broad adoption of PV globally. Silicone polymers possess key material properties that make them excellent candidates for photovoltaic module encapsulants and other materials for module assembly and installation that will help achieve these goals. These properties include UV stability, high optical transparency, excellent corrosion resistance, low moisture retention, wide temperature use range, and excellent electrical properties. This work will show why silicones offer improvements, over organic polymer photovoltaic encapsulants, of (1) increased photovoltaic module efficiency due to higher transparency at short wavelengths, and (2) improved long-term reliability. Actual array data comparing silicones to EVA encapsulated modules will be compared and results from accelerated aging will be discussed.
