| Outline of Final Research Achievements |
Single-walled carbon nanotubes (SWCNTs) are known to be electron acceptors from photo-excited chromophores, and hence their capabilities as electron mediators are investigated for novel organic photovoltaic solar cells.
The interactions between SWCNTs and photo-excited chromophores are studied. The wide variety of metal complexes (MCs) are adsorbed or electrostatically attracted to the SWCNT and their emission is quenched by electron transfer. In the case of organic hydrocarbons or dyes, they interact with the SWCNT to form electron donor-acceptor complexes and are not suitable for electron transfer.
Luminescence life time from excited MCs was investigated to examine the possibility of electron transfer to metallic and semiconducting SWCNTs. The experimental data suggest that the metallic SWCNT is a better electron acceptor. The information obtained from these measurements is useful to design the structure of nanocomposite used for organic photovoltaic solar cells.
