A topochemical process was used to synthesize {010}-faceted leaflike anatase TiO2 nanocrystals from exfoliated layered titanate nanosheets. A light scattering effect of the leaflike anatase nanocrystals with a crystal size of 300nm in length and 30nm in width was studied as a light scattering layer on a P25 nanocrystalline-TiO2 film for dye-sensitized solar cells (DSSCs). The light scattering layer...
Dye sensitized solar cells (DSSC) were fabricated using the dyes extracted from locally available natural plants of Mangosteen, Centella, Beetroot, Turmeric. Extracted dyes were analyzed using UV-vis spectrometer. Photo anodes were prepared by using regent grade TiO2 Powder. The TiO2 films were coated on Fluorine doped Tin Oxide (FTO) using doctor blade method and spray coating method. The film quality...
The temperature rise in the automobiles during the parking in sunny days is a critical issue which creates uncomfortable feelings for the passengers. Here we develop an affordable mini air conditioning system for the automobiles. The heat buildup in inside of the vehicle is fully investigated and the energy require for cooling is also estimated. Our finding provides an attractive solution to prevent...
The presence of large aggregates in TiO2 paste as a result of the poor dispersion of the TiO2 nanoparticles leads to a non-uniform nanostructured mesoporous TiO2 film consisting irregular pore sizes, a bumpy film surface, and low dye adsorption density. This study describes organic molecular modifications to TiO2 nanoparticles surfaces to improve the dispersion ability. Two kinds of organic molecules—ethylene...
