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."

  1. It's easier to predict than to make it happen.. by QuantumG · · Score: 5, Insightful

    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.

    How we know is more important than what we know.
  2. Efficiency is Missing by Geoffrey.landis · · Score: 5, Insightful

    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.

    ... Seriously, is there anything they CAN'T do?

    Make their way into an actual product people can buy?

  4. Re:Enough energy? by Overzeetop · · Score: 4, Insightful

    You mean 1/10000 is used for human power, right? Nearly all the power is used to keep the earth at its current temperature, else it would drift towards zero (okay, 2.7, but who's counting). Also, much of the useful energy is used to convert CO2 to O2, and in the process store C in H in various forms for powering the metabolisms of the earth's inhabitants. Luckily, those are overlapping purposes, as is solar collection for discretionary energy use by humans.

    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.

    Is it just my observation, or are there way too many stupid people in the world?
