Figure 3. (A) Volume resistivity and (B) contact resistivity 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 the maximum allowable volume and contact resistivity for solar cell interconnection, respectively. The squares indicate the mean values, and the error bars denote the standard deviation obtained from 9 (volume resistivity) and 28 (contact resistivity) measurements, respectively. ECA: Electrically conductive adhesive; PEG: polyethylene glycol.
