Market Trends, Materials & Manufacturing Processes

go PV 5. Lamination Process & PV Module Materials Encapsulant EPFL Front Glass Encapsulant Stringed cells Encapsulant Backsheet or Rear glass Main functions: • . Provide adhesion between components (cells-front glass, cells- backsheet, front glass-backsheet). Physical insulation - protect from weather (UV, rain, humidity, etc.); Electrical insulation - keep high voltage away from people and keep current from flowing out of the array circuit to ground; Good optical properties - couple as much incoming light as possible into the cells; GoPV Project | SUMMER SCHOOL PV SYSTEMS TECHNOLOGIES AND DESIGN 27
