摘要：
A simple technique was developed to fabricate a large-area TiO2 electrode layer using electrospun nanorods for dye-sensitized solar cells (DSSCs). Using this technique, we assembled DSSCs of area similar to 1 cm(2) consisting of a thin TiO2 nanoparticle layer and a thick TiO2 nanorod layer as electrode. The TiO2 nanorods were obtained by mechanically grinding electrospun TiO2 nanofibers. A titania sol was first spin-coated on a conductive glass plate and a TiO2 nanorod layer was next spray dried on it to fabricate TiO2 nanoparticle/ nanorod layers. These layers were subsequently sintered. The best- performing DSSC evaluated under AM1.5G (1 sun) condition gave current density similar to 13.6 mA cm (-2), open circuit voltage similar to 0.8 V, fill factor similar to 51% and energy conversion efficiency similar to 5.8%.
