Abstract	Flexible organic thin film solar cell device with Bulk Hetero-Junction (BHJ) structure was fabricated with blended conjugated polymer of PCDTBT：PC71BM as active layer. Surface of ITO anode for the organic solar cell device was treated with ozone. The organic solar cell device with bare ITO showed short circuit current density (Jsc) of 8.2mA/cm2, open-circuit voltage (Voc) of 0.73V, fill factor (FF) of 0.36, and power conversion efficiency (PCE) of 2.16%, respectively. The organic solar cell device with ozone treated ITO anode revealed distinctively improved performance parameters：Jsc of 9.8mA/cm2, Voc of 0.82V, FF of 0.43, PCE(η) of 3.42%.
