I–V characteristics of ITO/TiO₂/P3HT+PCBM/TiO₂/G-PEDOT (square) and ITO/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 = 5.7 mA/cm² Voc = 0.59 V  FF = 0.33  η = 1.38%, (circles) Jsc = 0.03 mA/cm² Voc = 0.22 V  FF = 0.25  η = 0.0016%.
