Paint Your Roof With Working Solar Cells Made from Grass Clippings

Popular Science -- Installing a solar roof on your home could one day be as simple as mixing your yard clippings into a stew of inexpensive chemicals and painting the resulting mixture right onto your rooftop. An MIT researcher has developed a method of manufacturing solar panels on the spot from agricultural waste, sidestepping the need for silicon and making ready-to-mix solar cheap and abundant virtually anywhere.

But first things first. What MIT’s Andreas Mershin has done here is pretty interesting. His chemical cocktail extracts the photosynthesizing molecules from plant matter--including chlorophyll--and stabilizes them such that they can be spread on a glass substrate. Said substrate is coated in nanowires and titanium dioxide “sponges” that help convert photons to electrons and then ferry those ele

I wouldn't touch a panel like this article states as grass degrades rapidly in a short period of time.

NHLiveFree Champion Author New Hampshire Posts:8,054 Points:1,275,040 Joined:Jun 2008	Message Posted: Feb 4, 2012 9:07:56 PM Ignore NHLiveFree Report Abuse remainder of this brief article - "and then ferry those electrons away as current. But you were waiting for the other shoe to drop, and now it shall: the conversion efficiency of Mershin’s paintable solar panel is just one-tenth of one percent. To even begin to make an impact, a solar panel needs an efficiency many, many times greater than that. But it’s a starting place, and to sweeten the deal the technology is cheap. Mershin hopes now that he’s put the technology in play, he or others will be able to build on it. More over at ExtremeTech." This is only a start in one more alternative for true renewable energy at a reasonable cost. That is simply what research and development is all about. At least this researcher is off his duff and working on improvements rather than just voicing the negative and complaining here. If you are unable to contribute to advancements for us, please don't complain about those that are, like Mr. Mershin. Please have some respect for his intelligent and ambitious efforts.

While the headline of this graduate thesis data dump sounds cool, the methane from the same grass clippings decomposing offers more potential energy. If the industry struggles to get investors for solar panels with 17.64% efficiency, so much so that the federal government bankrolls the industry, the 1.5% efficiency and $3 will get you a cup of coffee at Starbucks.
