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 [...]

Preparation of nitrogen-doped mesoporous TiO2 with a room-temperature ionic liquid

Hsiung T-L, Wang H.P., Wei Y-L, National Cheng Kung University, TW

A nitrogen-doped mesoporous TiO2 (N-TiO2) was synthesized using a room-temperature ionic liquid (RTIL) (C4mimBF4) as the template. By 1H NMR (Figure 1), interactions between Ti and nitrogen of the RTIL are observed. The nanosize mesoporous [...]

Mesoporous TiO2 thin-film for Dye-Sensitized Solar Cell (DSSC) Applicationv

Vats A., Shende R., Swiatkiewicz J., Puszynski J., South Dakota School of Mines & Technology, US

The DSSC is a low-cost device as compared with the conventional ‘p-n’ junction devices. This device utilizes about 5 m thick film of TiO2 nanocrystals to form a ‘bulk’ junction with a large surface area [...]
