Au-SiO2 core shell shows a plasmonic effect in dye-sensitized solar cells (DSSCs) as well as in Perovskite solar cells.
1- What does DSSC stand for?
2- We have fabricated Ag-SiO2 (core-shell) BY LASER ABLATION IN WATER.
You may download the abstract from my homepage in Researchgate:
S. Keshmiri, P. Parvin, S. Alipour, S. Z. Mortazavi ,"Nano core(Ag)-shell(SiO2) generation base on single stage laser ablation", EOS Conference on Laser Ablation and Nanoparticle Generation in Liquids (ANGE), Engelberg, Switzerland, 06/2010 .
ABSTRACT: It was shown that the repetition rate of laser shot affect on the core-shell formation.TEM micrographs illustrated that Ag nanoparticles have got to join each other to form the nanochains at the higher repetition rate(10HZ) whereas the nano spheres Ag were encompassed with SiO2 particles to create the core-shells at lower rate(1hz) . It was related to the two distinct formation mechanisms of coreshells and nanochains. Nano coreshell requires adequate time of formation with low rate of production whereas nanochain is a linear aggregate which take place at high generation rate of Ag nanoparticles.
Dear Sir,
Thanks for your answer!
DSSC stands Dye Sensitized solar cells. If you search in Google you will find ample publications.
To prepare core shell as you said, we do not have laser ablation technique.
If you have any other ideas, please suggest me. I would like to go by chemical route method.
_Thanks,
Chandrasekhar.
