Gallery: Sharp Breaks Solar Record With 43.5% Efficient Photovoltaic Ce...

 

Sharp just signaled a bright future for renewable energy as it achieved a new solar cell efficiency record of 43.5%, eclipsing its previous record of 36.9% set in November. Sharp shattered the efficiency record with its concentrator triple-junction compound solar cell, which uses a lens-based system to focus sunlight directly onto the cells in order to generate electricity. This latest breakthrough puts solar power one step closer to grid parity.

    This article is looks like it incorrectly paraphrased another one. Sharp did not break the record, but has matched the confirmed record that Solar Junction had in March of 2011. Note that this wasl not been published in the “Solar cell efficiency tables” as of version 40 which was published 24 JUL 2012.

    The highest submodule efficiency is38.5% +/-1.9% submodule byt DuPont et al. with a plit spectrum system. I think we can see module efficiency at 40% within three years. The work at ASU http://nanophotonics.asu.edu/paper/Caselli_OE2011.pdf combined with the Rainbow Concentrator by Sol Solution
    ttp://www.sol-solution.net/Technology.html is one path that may get us there.
