would it be possible to fire a laser at a solar panel in a vacuum and get back 100% of the energy?

solar panels are low efficiency overall. under 25%

why? where does the rest of the energy go?

can't the entire spectrum be converted into electric current with zero heat?

where's the problem?

No but you can get a laser receptor, it may burn something

you need gay light for that

No. You could get close with optical rectennas, but there will always be some amount of loss

hey anon, some energy would be lost as heat when the light hits the solar panel. hope this helps.

the answer is cost and it has been done for space power supply. the theoretical limit is like 80%.

nothing in your system has a 100% efficiency, it will still release some energy as heat, this is completely unavoidable btw, violates laws etc.

No, but since this in monochrome light you can get very close. Pentagon is working on this and had some news about such experiments a few years ago.

That is for broad band sun light.

there is no white laser light, it's just a few different wavelengths joined together with optics. it's the equivalent of using say three different lasers with three different cells, each of the three systems will have low efficiency. might as well go with the wavelength that you can make the highest efficiency panel for. stacked solar cells are for sunlight not laser light (per OPs question).

NO!
There is no such thing as a frictionless system and there is no such thing as 100.0000% efficiency. The is no perpetual motion machine, THERE IS NO FREE FUCKING LUNCH IN PHYSICS!!

From now on we post using sources because half of what you say is easily sectioned as nonsense because it spurs from the mind

>Researchers transmit energy with laser in ‘historic’ power-beaming demonstration
https://www.nrl.navy.mil/Media/News/Article/2504007/researchers-transmit-energy-with-laser-in-historic-power-beaming-demonstration/
>It was a long-range, free-space power beaming system - the first of its kind. Attendees that day, May 23, could see the system itself—the two 13-foot-high towers, one a 2-kilowatt laser transmitter, the other a receiver of specially designed photovoltaics. But the important part, the laser that was beaming 400 watts of power across 325 meters, from the transmitter to the receiver, was invisible to the naked eye.
>On one end of the of the testing facility — one of the largest test facilities for model ships in the world — the receiver was converting the laser energy to DC power, which an inverter was turning into AC power to run lights, several laptops, and a coffeemaker that the organizers were using to make coffee for the attendees, or “laser lattes.”
