Ditto for the C-PV, so while to do ...

It would be interesting to have a comparison in real, or better, a combined system or the thermal part would go through the stirling to be converted into electric.
Still a lot of unknowns
If you followed me in my modest contributions, perhaps you remember that as it stands, no one can do better.
Even if first of all we should not joke with the stirling, there are good applications like that of Romanian, we cannot deny it. So his "
generator-stirling " has its niche, no doubt. What I fear is the cost of maintenance. Compared to C-PV there is no photo.
To come back to the latter, it is not so much that the info dates that 1) it does not come from a lab but from the pre-industrial stage 2) that the info dates or not from the theoretical 46% there is always 37 % "effective", we can not do better, but if you want to compare with the poor performance of nuclear ?? !! 3) what we are especially expecting now (and it should not be too late) will be C-PVs free from noble materials to build them in large series, such as the return to certain forms of silicone in crystaline form, evolution of the good old silicon, and that in this field, I had also said that according to Sony's discoveries for C-MOS sensors, the future will be to differentiate the different wavelengths of photons, to capture them spectrum by spectrum ( RGB). We can therefore hope in the near future for a yield of 3x 20% = 60% gross WITHOUT C-PV! Then later 3x30% ... The ISE itself says it, they are going to deploy high efficiency and low cost sensors in this segment, that is their objective.
So, it's not so much that "
it's old", that we rather expect new developments from the start, indeed, and for that we can trust the Germans ...
If you want a track, we will surely hear about it with Solar Impulse III (SI3), because the saga will not stop at SI2 ... Since if with the latter they had reached 12% average efficiency (diurnal cycle VS nocture), we can reasonably estimate that with 29% better they will be much less annoyed by the weather windows, since they will be able to fly much faster (but not longer because the physiological limits of the pilots obliges, these have already been reached !!) So at least travel longer distances in one go, or take advantage of better corridors with favorable currents, which they would not have taken in the current state, for lack of sufficient reserves ... So more security too (but let them finish their first round the world!)
We are also talking more and more about hybrid sensors: photovoltaic + infrared!
We should also go and see what he will say at the 12th C-PV Convention ....

PS: in the meantime, Hats off to Fabio-Gel for discovering this "nugget"! That we come back to the debate with the stirling
