Cheap Paint-able Solar Cells Developed

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."

It's easier to predict than to make it happen..

I suppose. It's so strange these days. You see people doing research, then posing for a photo and making a press release. Then.. nothing. The promises and predictions don't amount to actual products that people can buy. But I suppose they do get you more grant money.

Efficiency is Missing

[Geoffrey.landis]

What is conspicuously missing from that article is any kind of a figure for the conversion efficiency of the devices they're making. Lots of researchers have been working on fullerines. What efficiency are they achieving? 5 percent? 1 percent? A tenth of a percent? Lacking any kind of number for efficiency-- preferably an efficiency measurement verified by the National Renewable Energy Laboratory-- tends to make me think that this is theory with no actual devices manufactured at all.
