Photovoltaic Manufacturing Technology (PVMaT): Annual Subcontract Report, 31 March 1994 - 30 June 1995

    Research output: NRELSubcontract Report


    This report describes work performed under a subcontract to the National Renewable Energy Laboratory under the Photovoltaic Manufacturing Technology Project. The objectives of this subcontract are to (1) define the problem of yellowing/browning of EVA-based encapsulants; (2) determine probable mechanisms and the role of various parameters such as heat, UV exposure, module construction, EVAinterfaces, and EVA thickness, in the browning of EVA-based encapsulants; (3) develop stabilization strategies for various module constructions to protect the encapsulant from degradative failure; (4) conduct laboratory, accelerated outdoor, and field testing of encapsulant, laminated test coupons, and full modules to demonstrate the functional adequacy of the stabilization strategies; and (5)implement these strategies. This report summarizes the accomplishments related to the above goals for the reporting period.
