Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A significant enhancement of efficiency in thieno[3, 4‐b]‐thiophene/benzodithiophene:[6, 6]‐phenyl C71‐butyric acid methyl ester (PTB7:PC₇₀BM) solar cells</bold> can be achieved by methanol treatment. The effects of methanol treatment are shown in an improvement of built‐in voltage, a decrease in series resistance, an enhanced charge‐transport property, an accelerated and enlarged charge extraction, and a reduced charge recombination, which induce a simultaneous enhancement in open‐circuit voltage (<italic>V</italic>_oc), short‐circuit current (<italic>J</italic>_sc), and fill factor (FF) in the devices. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v8vjpg4" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
