On the one hand, it's just another story about researchers boosting the efficiency of flexible, relatively inexpensive organic photovoltaic polymers: researchers at the New Mexico State University have integrated polymer and carbon buckyballs to raise organic solar material to 5.2% efficiency. On the other hand, it's another story about researchers boosting the efficiency of flexible, relatively inexpensive organic photovoltaic polymers: with so many groups taking so many different approaches to making organic solar efficient enough to be useful, we should see consumer-usable polymer pv sheets or even paint relatively soon, perhaps even before the decade is out.
