Japanese scientists eye 20% solar cell efficiency with new technology - report
Aug 29, 2011 - Scientists from Tohoku University and Kyoto University are working on a new solar cell production technology, targeting a conversion efficiency of 20%, Japanese daily Nikkei said on Monday.
The technology is for the making of polycrystalline silicon solar cells. According to the scientists, the very production process will not change and manufacturing expenses are to remain at current levels.
The team of scientists and Japanese silicon device manufacturer Daiichi Kiden Co plan to jointly develop solar power devices using the new technology. They intend to commercialise them in one to two years.
Photovoltaic installations have turned rather attractive following the March 11 earthquake and the subsequent nuclear crisis in Japan. To further speed up the sector's growth, a bill that calls for utilities to purchase all renewable energy produced by third parties at fixed rates was given the green light by Japan's upper house of parliament last week.
