Figure 2. (A) Yield stress and (B) lap-shear strength of an ECA containing 5 vol% silver as a function of PEG 200 volume fraction (0-10 vol%). Dashed black lines are to guide the eye, while dashed blue lines indicate minimum and maximum yield stress and minimum lap-shear strength required for solar cell interconnection, respectively. The squares indicate the mean values, and the error bars denote the standard deviation obtained from 3 measurements. ECA: Electrically conductive adhesive; PEG: polyethylene glycol.
