Next-Gen Glitter-Sized Photovoltaic Cells Unveiled
MikeChino writes "Sandia National Laboratories recently announced a new breed of glitter-sized solar cells made from crystalline silicon that use 100 times less material to generate the same amount of electricity as standard solar cells made from 6-inch square solar wafers. Perfect for soaking up the sun’s rays on unusual shapes and surfaces, the tiny solar cells are expected to be less expensive, more efficient, and have promising new applications in textiles, clothing, and building facade installations."
This technology will be mass produced in only 20 years.

Like most sensational announcements of breakthroughs in engineering on Slashdot; If I can't buy products that use it at my local hardware store or via Amazon for my iphone/laptop/electronic device, it might as well not exist.
So what that it was invented. The REAL story would be an announcement of a product that will be SOLD. This story is just a teaser.
Does anyone else notice every few months an amazing breakthrough in solar cells that will increase solar efficiency by 10^x power or lower the cost to nearly free? Meanwhile, the solar panels for useful applications are still expensive and space consuming?
I'm kind of getting tired of it.
"or lower the cost to nearly free?"
I think the term you are looking for is 'too cheap to meter' :-\
--- Mercutio was right.
I'd like to know how one would go about wiring these tiny solar cells up. It probably wouldn't be too bad on a flat surface but It doesn't seem like it would be very easy on flexible surfaces like textiles.
"Frequently wrong, never in doubt."
Efficiency alone is useless. You also must consider durability and cost. If something is 99.99% efficient, costs $ 1,000,000,000.00 per kW/Hr to produce and has a lifespan of 10 years, then, it's useless. If, on the other hand, it is 25% efficient, costs $ 5.00 per kW/Hr to produce, and has a life-span of 1 year, then "IT IS WICKED USEFUL!"

I'd imagine that in the same warehouse with the Ark of the Covenant, the process for Cold Fusion, the Cure for Cancer, and a thousand other sources of cheap energy....a spot for this gem is being cleared.
It would be interesting if these "glitter cells" could be suspended in some kind of "paint" or perhaps embedded in a capacitative tile. The paint especially would have a lot of interesting uses -- cover your car, for example.

I'm awfully tired of these articles predicting something will be better, cheaper to make and therefore much cheaper to buy.
Nothing in the history of the world that is better than an existing product has been sold for less.
Things end up being sold at a price very near what they're worth to the end user, which often has no relation to their cost of manufacture. Think of perfume, diamonds, or celebrity-diet plans.
Also for something exposed to the elements that has to last many years, there are so many ways to fail. Temperature cycles, moisture, UV, hail, corrosion-- all of these have to protected against,
and the cost of these goes up as you make the cells smaller and more fragile.
It's swell to have better (in some sense) cells, but that's just a small part of the overall picture.
Populated areas only make the problem worse. People go out to work at about the same time, go home about the same time, it gets dark at the same time. It is nice that you can power the filled offices from the empty homes, but where does your energy comes from when you switch on the light bulb when it gets dark? From storage, that's what. Only, with that many people doing about the same things, the individual problem just adds up.
