Nice list. Still, in my obviously biased view (as an engineer and ST flack), you're giving short-shrift to FD-SOI, which is faster, simpler and cooler--and BTW a finalist for top Energy Technology in the ACE Awards. FD-SOI's only disadvantage as a sub-30nm process technology is that it isn't being pushed by the industry's 600-lb gorilla.

And what about us software guys? ;-) My personal hot technology are user interfaces with gesture control, especially in the industrial context. I believe, we will see soon very innovative control systems for robots, for example. But my own 3D printer would be nice, too.

The 100% in my question above was assumed to be visible but I'm not sure if 'illumination' would right word. By definition, 100% efficiency would reflect NO light. You might say 'black' would be its color but 'invisible' might be closer to a correct answer, sort of a 'black hole' of sorts.

In the near term 30% sounds like may be close to limit but long term I don't see why efficiency couldn't approach 100%.

What is the cost differential for the competing solutions? # of processes or steps, cost per step, etching, doping, and vapor deposition costs per step.

Depends on the frequencys of illumination... any light is lost energy visoible or not. So black is best for PV efficiency

Nice one! Practically impossible to get 100%, I would settle any day to 30% efficiency with minimal degradation of efficiency over a decade at the least. MP Divakar

@Danbob: I usually use the print-mode so I can scroll down instead of clicking thru each page.

What color would a 100% efficient solar cell be?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
