Reduction of Collection Efficiency of Charge Carriers with Increasing Cell Size in Dye-Sensitized Solar Cell

Lee C-L, Lee W.H., Lee C-L, Lee W.H., Yang C-H, Yang H-H, Yang C-H, Yang H-H, National Cheng Kung University, TW

Changes in dye-sensitized solar cell performance related to active area size were investigated. The cell geometry was defined by introduction of a sub-electrode, which was uniform up to 4 cm2, and showed little change in [...]

Chang Y-H, Liao C-Y, Wang H.P., Wei Y-L, Fukushima Y., Guo T-F, Chiang Y-F, National Cheng Kung University, TW

The main objective of the present work was to study speciation of ZnO nanorods and the photoexcited electron transfer between photosensitive dyes and the ZnO nanorod arrays (Fig. 1) on the photoanode of a dye-sensitized [...]

Mesoporous TiO2 hollow spheres on a DSSC photoanode

Liao C-Y, Wang H.P., Lin H-P, National Cheng Kung University, TW

To enhance solar energy efficiency of a dye-sensitized solar cell (DSSC), high crystallinity mesoporous TiO2 hollow spheres (MHS-TiO2) have been coated on the photoanode. The MHS-TiO2 was prepared by calcination of the Ti(OBu)4 coated mesoporous [...]

Incorporation of plasma modified multi-walled carbon nanotubes into TiO2 photoanode for dye-sensitized solar cells (DSSC)

Chan Y.F., National Cheng Kung University, TW

Dye-sensitized solar cells (DSSC) are fabricated using photoanode comprises of nanocomposite material of TiO2 and multi-walled carbon nanotubes (MWNT) treated in situ by plasma and subsequent functionalization by grafting of maleic anhydride (MA). The carboxyl [...]
