I–V characteristics of ITO/PEDOT/P3HT+PCBM/TiO₂/Al (square), and ITO/TiO₂/P3HT+PCBM/TiO₂/G-PEDOT (circles). (a) I–V characteristics of device in dark condition, (b) I–V characteristics measured under white illumination (Xe lamp, 80 mW/cm²). Devices’ performance: (square) Jsc = 6.5 mA/cm² Voc = 0.58 V  FF = 0.32  η = 1.5%, (circles) Jsc = 5.7 mA/cm² Voc = 0.59 V  FF = 0.33.
