Again, only a few year away... They say that nanoantennas can absorb 80% of energy, but it's only infrared energy, so real efficiency compared to silicon cells

Again, only a few year away...
They say that nanoantennas can absorb 80% of energy, but it's only infrared energy, so real efficiency compared to silicon cells we'll have to see when they release it.
- iwwr 15y agoInfrared probably due to the limits of manufacturing (1/25th human hair diameter, or about 2 micrometers). Not sure what percent of the whole spectrum energy is possible to absorb.
- danmaz74 15y agoNot just that; it is also difficult to convert the adsorbed energy into usable electricity, and that for sure will cut down the efficiency of the process. The 80% claim for antennas to the 20% of silicon is really comparing apple to oranges.
