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."
There is a reason for this. Up until about the past 5 years there has been minimal manufacturing capacity globally. Everything was limited to laboratory experiments at universities or venture capital companies that like press releases. Now that we actually have companies making cells in volume the $/Watt has been driven down immensely. Take a look at first solar currently running somewhere near $0.90/Watt (solar cell production not end cost to consumer)
One hundred times less material? More efficient? Glitter?
Sounds suspiciously like sound bites designed by a PR office for pickup by the press. I thought that Slashdot editors saw through that sort of malarky.
I'm going to go out on a limb: does anyone know if the limiting factor in determining the costs of a solar cell is the amount of material used? I had thought it was the intensive processing required to create a solar cell, rather than the cost of the silicon, which, thanks to the gargantuan and heroic efforts of integrated circuit manufacturers, is vanishingly small for incredibly high quality (what other industry delivers seven 9s purity?). If the amount of material isn't relevant, then reducing it by a factor of 100 isn't that interesting, is it?
