I come back to see a friend who rides in an electric car, and who is a fan of energy alternatives, and we were talking about the use of solar photovoltaic to recharge batteries, with the disadvantage of the sensor surface that was needed in conventional ...
I spoke to him about the idea (developed elsewhere on econo ...) of concentration by lens, which makes it possible to multiply the pullable power of an element ... the residual problem being the cooling of the silicon, whose temperature can not to exceed 120 ° C ...
As I am interested in this subject, even if it is for the moment only theoretically, it seems to me (and this has also been mentioned elsewhere) that we could advantageously take advantage of these two types of sensors. ...
Here is a crobard to understand the idea:
A lens focuses sunlight on the photovoltaic cell, which is in thermal contact with the "hot" side of the Peltier cell.
The heat (IR) propagates through the substrates, and reaches the finned cooler, which is in thermal contact with the "cold" side of the Peltier.
The heat is dissipated by the flow of air passing between the fins, to maintain a Dt ° acceptable for the cell.
The electricity supplied by the two cells is recovered from this assembly.
One can imagine this assembly mounted on a "follower" turret which orients the plane of the cells perpendicular to the solar ray, so as to obtain the best performance.
This is called killing two birds with one stone!
What do you think ?
it is only for industrial (large industries).
