摘要：
We studied the photothermal stability of ethylene-vinyl acetate (EVA) laminates using accelerated testing in order to identify the reasons for its performance degradation on stacked amorphous silicon (a-Si) solar cells and EVA films. Stacked a-Si solar cells and EVA films were aged in accelerated tests under conditions of 1-SUN and 4-SUN. The results evaluated the deterioration of each separate level for solar cells made of three-layer stacked structure and EVA films. Spectral sensitivity and conversion efficiency were used as evaluation parameters. Spectral sensitivity could be used as an evaluation parameter after the accelerated test caused degradation on the EVA films. EVA films under 4-SUN accelerated testing revealed a phenomenon in which light transmission increased on the short-wavelength side of the spectrum. (C) 2003 Elsevier B.V. All rights reserved.
