March 17 (SeeNews) - Swedish solar technology developer Sol Voltaics AB has reached a 1-sun conversion efficiency of 15.3% in a gallium-arsenide (GaAs) nanowire array (NWA) solar cell.
It said in a press release on Tuesday that the result doubles the previous world-record for photovoltaic (PV) conversion efficiency using such cells.
Sol Voltaics believes that its Aerotaxy nanowire production methodology will make it possible to produce the III-V film at competitive cost and at great efficiencies. “We look forward to working with industrial partners on the integration of our technology on to Si cells so they may make the leap to 27% efficiency and beyond,” said CEO Erik Smith.
The Swedish company was founded in 2008 based on technology developed at Lund University in Sweden. It aims to improve the economics and efficiencies of solar PV modules with higher opto-electric conversion efficiency by using its proprietary nanomaterial film and Aerotaxy nanowire manufacturing process.
