MrSteve007: It is certainly interesting research, but at this point we've created a stable, long-life energy producing technology that doesn't really need any more efficiency upgrades. Even the product is almost dirt cheap these days (relative to payback). What solar energy needs is a proper nationwide installation, permitting standards and regulations.A majority of the cost involved with solar has to do with installation now, not equipment costs or longevity. A typical home's rooftop has more than enough space for PV to power all your needs for household and electric vehicles.
LasersHurt: Price per watt installed is still around $5 in the US right? But the actual cost of panels and hardware is a lot less, I've priced modules and equipment online recently.
HeadLever: Logggur: Why would you stop doing research on how to improve the efficiency of photovoltaics? You know you can upgrade technology while improving implementation at the same time.I think what he is getting at is the law of diminishing returns.
Cerebral Knievel: so they sunk a peltier junction to the back of a solar cell and tied it in parralel?

Cerebral Knievel: ajgeek: Cerebral Knievel: so they sunk a peltier junction to the back of a solar cell and tied it in parralel?I was thinking sodium battery.from what little bt I looked up on sodium-ion batteries... they aint ready for prime time.. if you are talking about sodium as a heat sink to store thermal energy? then that is proven tech for that type of thermal activity.I was thinking of peltier junctions.. solid state heat pumps.. the things that are used to make USB coffee warmers or cola chillers work, and are the basis of those camp stove / cell phone chargers they have now.add DC power and they make cold on one side and hot on the other, add heat or cold to the respective surface and they MAKE DC current.a lot of solar panels tend to get quite hot due to the fact that you are constantly pointing the damn things right at the friggen sun. so why NOT, slap a peltier junction on the back side of the panel? tie the out put of the PV panel to the PJ and see what happens?sounds like what the MIT kids are trying to do but with much fancier and expensive materialsor have I missed the point? and if my crazy ass scheme has glaring flaws I would like a more wizened farker to let me know how or why I may be a dumb ass for suggesting such a hair-brained scheme.

mark12A: Still no economical means of storing it. Won't become a substitute for grid power until we have a means of storing it for nightime use.
gnosis301 [TotalFark]I hope we're still subsidizing this kind of innovation.
