Hmmm....
Sandia also created the world's first LSD.
They be trippin'.
I’ve been reading about these innovations for 30 years. When does the application arrive that is cost effective without the government subsidy? I’ve two wood stoves in my home plus a small wood/coal version in the basement because they are economical given my circumstances. When do we see this technology make sense economically?
Paint, clothing, car batteries, rooftop coverings, a large list of uses if they perfect this enough to have real world application. Would this translate into computer chip tech in any way? Thanks for the thread.
> Would this translate into computer chip tech in any way?
These solar cells, typically, used to be chips. It is a recycling aspect of the semiconductor industry. Take all the transistors, diodes, op-amps, memory, and computer chips that are defective, grind them up and call the ground up dust amorphous silicon. Then, heat them to a vapor and deposit the vapor on whatever you want and it forms a silicon photocell capable of generating electricity in the presence of light. OR you can use the re-deposited vapor as a biasing layer in making LCD video displays.
They’re already doing this.
As far as alternatives are concerned, solar probably has the greatest potential. I know that solar collecting crystals have been produced in a lab that are some 80% efficient but can’t be mass produced yet. Current technology can mass produce solar collectors that are some 20 to 30% efficient.
If we can ever mate mass production with 80% collection efficiency (at a reasonable cost) we’ll see solar take off.
From what I’ve read, 80% efficient collectors could mean solar collectors for the home that are only a few square feet rather than dozens of square feet. In fact with that kind of efficiency, solar starts to become viable even in cloudier and more northerly locations.
Thanks. I’ve long thought that someday, and maybe soon, fast computers will be a glass ball filled with chips of the consistency of gas or vapor.
I’d like to know what companies are trying to commercialize this approach. They would be a far better financial bet than the ones doing windmills and (of all things) carbon sequestation.
Windmills are at their peak efficiency as far as I can tell. Not too shabby for thousand year old technology. LOL
And even the best of the best still stop when the wind does. We have come so far. /s
80% is a large number.
The present DARPA goal is 50%.
Even 50% efficiency would be a huge leap forward.
You’ve still got to get around the work function. This puts a theoretical limit on the efficiency of these devices. Now could we chemically change the work function........?????
No, Laz, its just you trippin'. Sandoz developed acid, not Sandia.
No, you’re thinking of Santa.
It depends on who the Government is rooting for and picks as a winner.
The special lab produced solar cells are strugling to get to 40% effiency.
Mass produced solar cells vary from the teens for crystaline and less than ten percent effiency for amorphous and nonsilicon cells.
I just love these kind of articles and was guilty of producing a few when I was in research. It is the classic, “At this point all the big problems are solved and it just needs to be put into production.”
Rolling eyes......
