Synthesis, characterization, and photovoltaic properties of TiO2/CdTe core-shell heterostructure for semiconductor-sensitized solar cells (SSSCs)

Synthesis, characterization, and photovoltaic properties of TiO2/CdTe core-shell heterostructure... The present work represents successful synthesis of CdTe-sensitized TiO2 nanoarray thin films by two simple chemical routes. Here, we report the sensitization of TiO2 nanoarrays with CdTe nanoparticles through the electrodeposition technique at ambient condition. The electrodeposition of 30 min leads to the formation of shell of CdTe nanoparticles over TiO2 nanoarrays. This core-shell formation structure was further confirmed by TEM and HR-TEM analysis. Optical absorption and photoelectrochemical study revealed that the TiO2/CdTe core-shell heterostructure extend the absorption edge of titania in the visible region of solar spectrum; it also facilitates the efficient charge transport and reduces the recombination losses. The maximum photoconversion efficiency of 0.32% is obtained for TiO2/CdTe core-shell semiconductor-sensitized solar cells (SSSCs). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Solid State Electrochemistry Springer Journals
