Cheap Paint-able Solar Cells Developed 254
Invisible Pink Unicorn writes "Researchers at New Jersey Institute of Technology have developed an inexpensive solar cell that can be painted or printed on flexible plastic sheets. According to the lead researcher, "Someday homeowners will even be able to print sheets of these solar cells with inexpensive home-based inkjet printers. Consumers can then slap the finished product on a wall, roof or billboard to create their own power stations." The team combined carbon nanotubes with tiny carbon buckyballs (fullerenes) to form snake-like structures. Add sunlight to excite the polymers, and the buckyballs will grab the electrons. The article abstract is available through the Journal of Materials Chemistry, with an illustration of the technology."

Does it seem to anyone else like carbon nanotubes are modern snake oil? Seriously, is there anything they CAN'T do?

We already subsist off of solar energy, for the most part - it's just our source happens to be stored a long time ago. Nuclear is about the only source (okay, geothermal, too) that isn't a form of solar energy. It's not so much the energy, it's the ability to store it in usable forms.

Therefore, what is the total energy budget of this material?
If they have to be replaced frequently, produce low wattage, and cost a lot of energy to produce and deploy, then silicon PV cells that last 35+ years at 15-25% efficiency might still be better, even though the silicon cells cost a lot of energy to produce, deploy, maintain and recycle. Or maybe this tech is better.
I wish every journalist covering the accelerating solar power industry would always answer those basic questions. Otherwise, it's just science fiction dressed up as propaganda.

VCs are usefully once you have a prototype and a proof of concept to actually do the engineering work and deliver a product. That takes 1-3 years on average and this is a timeline VCs are happy to cope with.

CCDs are probably closer since they both use the pv effect, and how much did a 10Mp image sensor cost only 10 years ago? Sh1tloads, if they were even making them at all. Now they only cost a few dollars.
The basic idea is that once you have done the research so the design and the process are set up, you just churn out the same thing again and again. Contrast this to, say, a car, where there are thousands of parts, of all sizes, made out of all sorts of materials then assembled either by hand or by robot.
I call for government subsidies! Discuss.
