Abstract

A significant enhancement of efficiency in thieno[3,4-b]-thiophene/ benzodithiophene:[6,6]-phenyl C71-butyric acid methyl ester (PTB7:PC ₇₀BM) solar cells 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 (V _oc), short-circuit current (J_sc), and fill factor (FF) in the devices.
