A Layer of Graphene, A Layer of Nanowires…

Combine nano-anything with graphene, and that seems to describe most of what’s driving physics and chemistry laboratories at our major universities.  The blog reported last week on Princeton researchers who’ve created a thin, flexible solar cell that absorbs 96-percent of received light and draws energy from off-axis and varied wavelengths of light. MIT researchers, too, have created a thin, flexible solar cell, but one based on layers of flexible graphene sheets, each coated with a layer of nanowires.  Besides flexibility, these sheets offer transparency, enabling their use on windows as well as other surfaces. David Chandler, reporting for MIT states that the new cells may prove to be far less expensive than today’s silicon equivalents, which require high-purity silicon that undergoes crystallization …
