Fj. Pern et al., EVA ENCAPSULANTS FOR PV MODULES - RELIABILITY ISSUES AND CURRENT RESEARCH-AND-DEVELOPMENT STATUS AT NREL, Renewable energy, 8(1-4), 1996, pp. 367-370
We briefly summarize ethylene-vinyl acetate (EVA) reliability issues a
nd report our R&D results. These results include EVA degradation effec
ts, discoloration factors, approaches to mitigate the EVA discoloratio
n, improved photostability of modified EVA formulations, and plans to
identify the best encapsulation schemes and to develop appropriate met
hodologies for predicting service life of PV modules.
