While researching the unique electrical properties of single-walled carbon nanotubes (SWCNTs), researchers have demonstrated the nanotubes’ ability to capture and store one electron per 32 carbon atoms in a SWCNT. The stored electrons can be readily discharged on demand with the addition of an electron-accepting dye, significantly increasing the photocurrent and photoconductivity of electrical systems.
