Investigation of Test Methods, Material Properties, and Processes for Solar Cell Encapsulants. Eighth Annual Report

摘要

The historical development of ethylene-vinyl acetate (EVA) is presented, including the functional requirements, polymer selection, curing, stabilization, production and module processing. The construction and use of a new method for the accelerated aging of polymers is detailed. The method more closely resembles the conditions that may be encountered in actual module field exposure and additionally may permit service life to be predicted accurately. The use of hardboard as a low cost candidate substrate material is studied. The performance of surface anti-soiling treatments useful for imparting a self-cleaning property to modules is updated.
