Well, once you start looking at the options with solar energy things look pretty rosy right? I mean in ten years from now a third of the produced energy will be solar or otherwise green ( wind power, biomass… ). Most building will be energy self suficient with those fancy dyes on every window and spray-on solar cells everywhere. Right? Well not quite. Everything looks fine until you realize that to produce solar cells NF3 is used. NF3 or nitrogen trifluoride is a gas thats used in the production of LCD displays and solar cells. Unfortunately it is also a very potent green house gas.

Fortunately The Linde Group a world leading producer of gasses has found out that NF3 can be replaced with fluorine gas. Fluorine has no effect on the green house effect and its readily available. On top of that it also speeds the production process thus lowering the costs of solar cells altogether.

A new invention that would allow domestic window to function as solar panels was recently invented by scientist at MIT in Boston. The real invention is a special coat that aplied to the windows conducts some of the light to the edges where the solar cells are. This has several advantages it allows for smaller solar cells lowering the cost of the installations, concentrates the light raising the eficiency as the solar cells are more eficient at higher light intensities. Another major saving is the unobtrusive installation that requires just a coat of the revolutionary material thus eliminating the need of expensive roof mounted panels or concentrators that need further cooling.
