| Outline of Final Research Achievements |
In this project, I have design and synthesized few potential new dyes covering a short and a long wavelength light based on metal complexes and metal-free organic dyes. Using these new sensitizers, I have successfully fabricated Multi-dye (UV-dye, VIS-dye and NIR-dye) sensitized dye sensitized solar cells with these novel new dyes. Optical and electrical investigation shows that small UV-dyes can suppressed strongly the TiO2 injected electron recombination with the electrolyte(I3-). These triple dye co-sensitized solar cells showed a panchromatic response with an IPCE >70% over the entire visible spectrum extending to the NIR region, suggesting their usage in indoor applications. The research results are presented at 8 international scientific meetings and also published in 17 peer reviewed scientific journals.
