Caltech gurus whip up highly efficient, low cost flexible solar cell
Solar cells are cute and all, but let’s be real — these things are far too inefficient for mainstream use. Scientists at the California Institute of Technology are working hard to remedy that very issue, and they’ve recently concocted a “new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons.” The solution relies on arrays of long, thin silicon wires embedded onto a polymer substrate, which uses just a fraction of the expensive semiconductor materials required by conventional solar cells. According to professor Harry Atwater, these cells have “surpassed the conventional light-trapping limit for absorbing materials” for the first time, and we’re told that the arrays can convert between 90 and 100 percent of the photons they absorb into electrons, and yes, that does mean that they have a near-perfect internal quantum efficiency. Hit the source link for all the technobabble, and cross your fingers for this stuff to get the honored approval of the Governator.

Oki shows off prototype LED-based HUD, coming soon to a jalopy near you

Currently, the only way you’re getting a heads-up display in your whip is if you pay two arms and a leg for it. By and large, mid-range and low-end vehicles have been completely removed from the HUD fun, but all that could be changing thanks to a new effort from the crew at Oki Digital Imaging. Said outfit recently demonstrated a LED-based alternative that measures 1.1-inches in size and is constructed using the company’s own EFB (Epi Film Bonding) process. Without getting too deep in the technobabble, the newfound process consumes less power, requires a simpler heat sink and boasts an all-around simpler structure. The end result? A far less expensive heads-up display, which — if all goes well — will begin sampling by the end of next year and could hit low-end cars, mobile phones and other handhelds shortly thereafter. Oh future, how we love thee.

Physicists calculate the end of Moore’s Law, clearly don’t believe in Moore’s Law

If you’re looking for pundits with an end date for Moore’s Law, you don’t have to look far. You also don’t have to look far to find a gaggle of loonies who just knew the world was ending in Y2K, so make of that what you will. The latest duo looking to call the demise of the processor mantra that has held true for two score comes from Boston University, with physicists Lev Levitin and Tommaso Toffoli asserting that a quantum limit would be achieved in around 75 to 80 years. Scott Aaronson, an attention-getter at MIT, expects that very same limit to be hit in just 20 years. Of course, there’s plenty of technobabble to explain the what’s and how’s behind all this, but considering that the brainiacs of the world can’t even agree with Gordon Moore’s own doomsday date, we’re choosing to plug our ears and keep on believin’ for now. Bonus video after the break.
