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

Thats perfect. Thanks for the tip.

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

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
