Mitsubishi Electric Corp. says it has improved its conversion efficiency rate for a 150 mm x 150 mm, practical-size multicrystalline silicon photovoltaic cell from 18.6% to 18.9%. The company says the advancement represents a new world record.
In addition to the technology already developed by Mitsubishi Electric to improve the photoelectric conversion efficiency rate in multicrystalline silicon PV cells, the company says it has developed a new method to efficiently absorb infrared rays in sunlight, thus achieving the 18.9% milestone.
The company says it will begin introducing this cell technology into mass-produced PV modules in April 2010.
