Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201470237-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>S.‐W. Tsang, F. So, and co‐workers use charge modulation electroabsorption spectroscopy (CMEAS) to determine the VOC loss in several polymer‐fullerene solar cells. Based on their data, they conclude on page 6125 that the <italic>V</italic>_OC loss is due to the low dielectric constants of the polymers. The photovoltage loss is found to be close to zero if the dielectric constant of the polymer‐fullerene blend is close to a value of five. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1c43c7vj" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
