Project Description

The project involves research on Photochemical and photoelectrochemical methods for the production of alternative energies from renewable energy. The main focuses are on development of alternative energy resources to fossil fuels and removal of water pollutants.

  1. Fabrication of dye-sensitized solar cells, bulk hetero junction solar cells and hybrid solar cells for the conversion of solar energy into electrical energy.
  2. Develop a device with multiple bandgap tandem cells and thin-film photocatalyst that can be activated by UV, visible and IR photons for the economic production of hydrogen and oxygen through water splitting.
  3. Chemical, Electrochemical and Photochemical methods for the purification of water.

Achievements of the Project

  • The project successfully demonstrated use of n-p junction electrode for the control of charge recombination in dye-sensitized solar cells.
  • Investigated the effect of coating of thin insulating oxide layer on semiconductor electrode materials on performance on solar cell efficiency and photocatalytic activities.  The mechanistic aspects of these processes were established.
  • The use of p-type oxide semiconductors in dye-sensitized solid-state solar cells was successfully demonstrated.
  • Electrochemical and phot ochemical methods for the purification of water were developed.
  • Photochemical and photoelectrochemical methods for the production of renewable energy such as H2 were investigated.
