Abstract

Inverted polymer solar cells (PSCs) were demonstrated to improve the performance using 1-Benzoyl-2-thiourea (BT) as surface modifier on sol-gel ZnO. X-ray photoelectron spectroscopic (XPS) results showed the formation of N-Zn bonding and the reduced oxygen vacancies (V _o ), indicating BT chemisorbed on V _o sites of ZnO surface to passivate O defects. From ultraviolet photoelectron spectroscopic (UPS) data, the BT modified ZnO (ZnO/BT) showed decreased work function (WF) due to the interfacial dipole, enhancing the electron transportation. Besides, the phenyl group of BT provided the hydrophobic surface not only good contact with organic active layer but also a good prevention of moisture, improving the interfacial compatibility and long-term stability. Accordingly, PSCs with ZnO/BT possessed 9.16% of power conversion efficiency (PCE) higher than 8.16% of the pristine ZnO.
