One of the limitations of solar photovoltaic systems is that, at the current state of the technology, no more than a quarter of the energy from the sun is converted to electric current. Most of the rest of the energy is lost as waste heat.

But Vinod Khosla, the founder of Sun Microsystems and now a technology entrepreneur and alternative-energy venture capitalist, says he’s found a solution that doubles or even triples the energy yield — a gargantuan leap in a field where engineers exult over the most incremental gains.
