Today Global Solar unveiled a new type of flexible solar module that builders can stick directly on the roof, rather than constructing racks to hold heavy glass-covered cells. The modules won’t cost less than traditional arrays, at least initially, but they make it easier to include solar power at the time of construction and, without the racks, can cover a greater portion of the roof and provide more power.

Bulky and expensive photovoltaic panels are so 2008. What does the future look like? Entire buildings, rooftops and even windows spray-painted with revolutionary nanoparticle inks that channel solar power into a thin, semi-transparent and relatively inexpensive medium. Sound crazy? Not at all, according to one group of chemical engineers.
