Looks like solar panel technology will be improved and cheaper soon! Yippie. It'll make it more practical for us to get away from generators and shore power. It looks like we'll have to wait a year or two before we start seeing them. http://www.technologyreview.com/read_article.aspx?id=16736&ch=biztech | ||

Nice find JW ! Now couple that up with this http://www.lbl.gov/Science-Articles/Archive/MSD-full-spectrum-solar-cell.html and get that electric bus that Paul found on ebay the other day (item 4634553861) and you've got a..... ..... well, you've got a something...  | ||

Yes well written "infotisement", the concept should attract lost of investment. This product should do well in very cold regions to compensate for the lower hours of light and make them just as $per watt cost effective as using current technology in southern areas that have a higher average total hours of sun up hours. I am sceptical about the blanket claim of lowering the cost a per watt figure "up to" 75% as that does not take into account the loss of eficiency a 3 times hotter photo voltaic takes on as it's temperature heats up unless phase two of the investment sceam will be to develop effcient high temperature photovoltaic cell or a energy efficient way to deal with the cooling needs like recouping the effort in cogeneration to power a sterling engine or a thermalcouple driven pump or generator. (How much "waste" stored heat can one use in a warm climate?) Nice innovation to consider using holographic prisms as cheap compact collector/concentrators. Thanks for sharing. | ||

TH, did you know that, when you connect a load to an illuminated solar panel, you actually cool it, because the power going to the load is otherwise dissipated within the panel? Well, it's true. If the holofilm is designed to convey to the cells only those wavelengths that the cells are designed to absorb, then there is no extra energy to heat the cells, eh? | ||

I believe they covered the heating issue in the description, as Herman said, with directing particular parts of the spectrum towards the cells, and the rest away. | ||

Yes I was aware of that herm. thankyou kindly for the clarification, as my vague comment may have led others to confusion about the facts. Always the danger of over simplification. As my practical is somewhat outdated , one of the early walls with PV was that heat barrier that lowered the "solar too / electron transfer : ratio" as the temperature rose toward critical. This question calls for some prototype accusation and independent testing while the fuel market is still artificially over-inflated (supply & demand is the best window to get this new stuff invested in and into the production stage) Here is hoping to go with the doing. Which I guess we are all a small part of as nothing get into production without the word getting out first it seems. Isn't that the final word in demand with this internet enhanced efficient marketing??? |
