In the effort to produce inexpensive, easily manufactured sources of sustainable, renewable power, solar cells continue to be a major focus - particularly flexible solar cells that can be applied directly to surfaces. Flexible solar cells are nothing new, but the methods by which they are made have progressed significantly in recent years.

One company, Konarka Technologies of Lowell, MA, recently announced that they had demonstrated the ability to manufacture solar cells by inkjet printing. The company's Power Plastic(R) solar cell technology - which is the result of a project originally funded by the U.S. military - uses a wider range of the light spectrum than conventional solar cells. All visible light sources - not just sunlight - can be used to generate power. It can be used virtually anywhere there is a light source and a battery.
