Bluglass Technology for Producing High Efficiency Solar Cells |
|
Bluglass was originally established to commercialise a low cost technique for producing LEDs. The technology involves the Remote Plasma Chemical Vapour Deposion (RPCVD) process for producing gallium nitride films. This low temperature process can also be applied to the production of photovoltaics, where their process can be used to produce films with a higher indium content, wich can effectively boost the efficiency of the solar cells.
