Figure 1.

(A) Comparison of the UV–vis spectrum, recorded for a PEDOT layer (Q_pol = 25 mC cm^–2), at E = −0.9 V in 0.1 M Na₂SO₄ solution, saturated with Ar with the irradiance spectrum of the solar simulator. (B) Photovoltammogram recorded in 0.1 M Na₂SO₄ saturated with Ar for a PEDOT film, electrodeposited with optimal polymerization charge density (Q_pol = 50 mC cm^–2) on glassy carbon electrode. The sweep rate was kept at 2 mV s^–1, while the light-chopping frequency was 0.1 Hz. (C) Maximum photocurrent vs polymerization charge density plot.
