Conductive mesh based flexible dye-sensitized solar cells

Conductive meshes are used to replace transparent conducting oxides (TCOs), which are commonly used in electrodes of dye-sensitized solar cells (DSSCs). The TCO-less flexible working electrode could be sintered under 400-500 degrees C. A preliminary result that open-circuit voltage (V-OC)=650 mV, short-circuit current density (I-SC)=4.5 mA/cm(2), and efficiency (eta(AM1.5))=1.49% (100 mW/cm(2)) is obtained from the liquid-type DSSC. The incident light could be dispersed uniformly inside the electrode. Testing results of the double-counterelectrode cell indicate that the transmission of electrolyte is not the rate-determining step. The dense TiO2 layer is critical in improving the cell's performances. (c) 2007 American Institute of Physics.
