摘要: Abstract We present the results of experiments which demonstrate that a sinusoidal variation in long-term, STC-corrected, outdoor performance PV modules is caused by seasonal spectral changes received sunlight. This may be factored out to increase precision studies. use this result (a) quantify rate EVA degradation observed Negev desert under natural 1-sun conditions and (b) identify principal source “summer recovery” amorphous silicon cells.
