Caption: The new solar concentrator design (right) from UC San Diego collects sunlight with thousands of small lenses imprinted on a common sheet. All these lenses couple into a flat “waveguide” which funnels light to a single photovoltaic cell. Older system designs (left) require many photovoltaic cells which each need to be aligned and electrically connected.
