摘要

The insertion layer of TiO2 between polymer-fullerene blend and LiF/Al electrode is used to enhance the shortcircuit current Iso and fill factor (FF). The solar cell based on the blend of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and C60 with the modifying layer of TiO2 (about 20nm) shows the open-circuit Voc of about 0.62 V, short circuit current Isc of about 2.35 mA/cm2, filling factor FF of about 0.284, and the power conversion efficiency (PCE) of about 2.4% under monochromatic light (500nm) photoexcitation of about 17mW/cm2. Compared to cells without the TiO2 layer, the power conversion efficiency increases by about 17.5%. Similar effect is also obtained in cells with the undoped MEH-PPV structure of lTO/PEDOT:PASS/MEH-PPV/(TiO2)LiF/Al. The improved solar cell performance can be attributed to enhanced carrier extraction efficiency at the active layer/electrode interfaces when TiO2 is inserted.
