I'm amazed nobody has mentioned the work of Martin Green at the University of NSW in Australia. For many years, Martin has held the world record for solar cell efficiency for more than a decade, continually pushing the upper bound. I believe the current record is around 30%, as described here. Martin was the recipient of the Right Livelihood Award, aka the "alternative Nobel Prize" in 2002, and the Australia Prize in 1999. He appears to be the Nakamura (world leader in the development of LEDs) of the solar cell world.
