“So the solar funnel operates the same way you would think a regular funnel would work if you were to bring it outside in the rain. In fact, that’s a very good analogy. You know if you think of rain droplets like photons, you know, small packets of light, what the funnel actually does is it concentrates these photons down in space and concentrates them down to a small spot. And if you have a photovoltaic or a photo detector there, then you can greatly enhance the performance of this device.”

20. SOUNDBITE (English) Geraldine Paulus, graduate student, Strano Research Group:
“The sunlight excites the nanotubes that are in the outer layer of the fibre, and because of the different properties that make up the nanotubes in the different layers, the light is being funnelled to the core of our construction, of the fibre. That’s where it is emitted at a wavelength that is specific to the nanotubes in the core of the fibre. So basically we’ve spatially and energetically focused the light.”
21. Group shot Paulus and Han
22. SOUNDBITE (English) Geraldine Paulus, graduate student, Strano
Research Group:
“So once we noted that the fibre fluoresced and that it gave light as you see here on this image, we analysed the wavelengths of this light and the intensities with the computer and compiled all the data in the plot that you see here.”

24. SOUNDBITE (English) Geraldine Paulus, graduate student, Strano Research Group:
“When the light travels, when the energy travels from one type of nanotube to the other type of nanotube, it loses a bit of its energy.
This bit of energy is determined by the difference in bandgap between the two types of nanotubes. If you choose two types of nanotubes which have a bandgap that is pretty much the same but one is a little lower than the other, then the energy lost in the transition will be mimimalised. So we could improve our invention by choosing two types of nanotubes that are more closely related, propertywise.”
25. Various setups Michael Strano at desk
26. SOUNDBITE (English) Michael Strano, Associate Professor of Chemical Engineering at MIT:
“Instead of having the entire roof be covered with say a brittle piece of silicon photovoltaic, you could then start to think about having a much smaller array of devices maybe embedded into plastic and then using a solar concentrator to make up for the decrease in area that you’ll find. So this tool can help engineers to make more robust photovoltaic technology.”
