Shares in green technology company BlueGlass have risen by more than a third after it announced it has signed a licence agreement with S Korean group BLK and would look for opportunities in the solar PV market. BlueGlass was listed September 2006 to pursue commercial opportunities from technology developed at Macquarie University to allow gallium nitrides to be deposited on glass wafers at lower temperatures than conventional means. Not only is it a cheaper process, it does not emit toxins. Until now, the firm has focused on the LED market, which includes traffic lights, computers and mobile phones, but the agreement with BLK will look at opportunities to use the technology in the household and commercial lighting markets.
