a The surface treatment and improvement of interfacial contact considerably enhance the cyclic performance of OECDs. (b)-(e) show the images of the as-prepared PProDOT film on bare ITO, PProDOT on bare ITO after 140 cycles, PProDOT on roughened ITO after 380 cycles, and PProDOT on SiO2 NP treated ITO after 8500 cycles, respectively. The cyan dot lines indicate the electrolyte front line. (f)–(h) show the cyclic voltammetry responses of PProDOT film on bare ITO, roughened ITO, and SiO2 NP-treated ITO, respectively.
