    Merits of plastic substrates

    what about resistance to ultraviolet? Certainly plastic substrate not last as long as say, stainless steel foil?

    • "However, all organic solar cells made to date suffer from degradation upon exposure to UV light, and hence have lifetimes which are far too short to be viable. The conjugated double bond systems in the polymers, which carry the charge, are always susceptible to breaking up when radiated with shorter wavelengths. Additionally, most conductive polymers, being highly unsaturated and reactive, are highly sensitive to atmospheric moisture and oxidation, making commercial applications difficult."


      Organic cells are cells made from carbon compounds. CIGS is not a carbon compound. The plastic Ascent uses does not carry the charge. The charge is carried by the cigs.

      You have, however, uncovered a possible reason for Konarka http://www.konarka.com sending their samples to cell phone makers instead of the integrators of modules for outdoors use.

      Good work! but not really applicable to Ascent.

    • p0sthumanfuture,

      Q. Since you told Ms. Granny to never address you again or you will have her removed from Yahoo...

      Could you please post a link so I can get "YOU" removed from Yahoo?

      Thanks,

      Turd.Trader :)

    • degradation upon exposure to UV light

      much cheaper cells that are based on inexpensive plastics

      are always susceptible to breaking up when radiated

      being highly unsaturated and reactive,

      are highly sensitive to atmospheric moisture and oxidation,

      Polymer processing
      The invention of conductive polymers (for which Alan Heeger, Alan G. MacDiarmid and Hideki Shirakawa were awarded a Nobel prize) may lead to the development of much cheaper cells that are based on inexpensive plastics. However, all organic solar cells made to date suffer from degradation upon exposure to UV light, and hence have lifetimes which are far too short to be viable. The conjugated double bond systems in the polymers, which carry the charge, are always susceptible to breaking up when radiated with shorter wavelengths. Additionally, most conductive polymers, being highly unsaturated and reactive, are highly sensitive to atmospheric moisture and oxidation, making commercial applications difficult.

      IMHO: I will go out on a limb and predict ASTI will see $5 before $20

      I just "flat out" do not believe "Paper Thin Plastic" is the answer, ASTI is a scam. Go ahead, Flame me, I hold No position in ANY solar company, researching this is really entertaining!

      Who ever said Da Ja Vu ASTI is the new DSTI, I agree... this research just makes me want to market order 1000 ENER

    • p0sthumanfuture: what does LMFAO mean?

      Thanks for your investment advise/help, BTW who picks up your trash?

      So far I'm happily involved in JNJ just waiting for this high risk stuff to bottom, my first JNJ dividend comes next month, right on! (37.5 cents per share, come on down.

    • Norsk Hydro doesnt give a $hit? ASTI is a tax writoff? OMG!!!!! you must be out of your mind! Just because that is your disgusting attitude toward life that is not how you build a billion dollar company LMFAO. You need to get a job buddy for real im trying to help you here you are not cut out to be investing . People like you are a waste of flesh and should be recycled as organ donors you are a poor excuse for a biped my friend.

    • I have $138 dollars in my wallet, I decide to buy my kid a science learning toy for $9 dollars, My kid and I play with the toy and as luck would have we lose or break the toy, we both laugh at the toys fate and find something else to occupy our time, like a basket ball game in HDTV!


      Norsk Hydro has $138 Million dollars in corporate profits sitting in a bank account, it must either pay taxes on it or risk it possibly making the company an even greater return. It knows a thing or two in energy and alternative energy business; hence, it invests or risks $9 million in ASTI with an uncertain probably of success (that I don't know) in plastic monolithic CIGS solar cells... I cant finish the story because we don't really know the out come out side a small sample test conducted in a laboratory; additionally, basket ball season is about over!

      Point: win or lose Norsk Hydro either increases their revenues some how, some way, or writes off the loss and pays less tax, they don't give a $hit, it's all in a day's work.

    • E Signal? Right side of the trade?

      Sorry, we have very different strategies.

      I'll be holding onto my shares for years which means I'll end up 'shorting the box' somewhere down the line but not anytime soon. There's just too much upside potential.

    • "These organizations have unlimited funds, they don't give a $hit who's technologies they use, they just want to do their job, make their living etc."

      What about Norsk Hydro? Do they give a shit?

      Come on now, tell us how you really feel about Norsk.

    • "(Norsk, NASA, the USAF and Ascent Solar are saying this might exist, and are desperate for it to exist, as are you desperate to make a killing in the stock market.)"

      Desperate?

      Not really, just looking forward to getting off the grid and driving a fuel cell powered Morgan http://www.carmagazine.co.uk/first_official_picture.php?sid=580&page=1
