Solar PV:What happens to the lost energy?inductive recovery?

AI Thread Summary
The discussion centers on the efficiency of solar photovoltaic (PV) panels, highlighting that much of the absorbed energy is lost through reflection and heat generation. It is noted that heat is primarily produced by electrons that are excited but fail to be captured effectively. The idea of using a magnetic field to recover energy from these unutilized electrons is proposed, likening it to inductive recovery. However, responses clarify that the movement of electrons between energy states does not generate a coherent magnetic field suitable for energy capture. Overall, the conversation emphasizes that while innovative ideas are welcome, existing research has likely explored many avenues for improving PV efficiency.

Hi there, I am new in here, thanks for any reply.
I took same title of a previous closed 3D by pranj5.

As understood main part of the energy absorbed by PV panels goes in reflection and heat.

The heat origins mainly in electrons that are excited but not enough to jump or they jump but they are not captured at the cathode.

I was thinking... PV panel are usually diamagnetic... if during operation we invest it by a magnetic field can we recover the work of those electrons that were not so lucky?
a sort of inductive recovery for photovoltaics to increase efficiency...

any study in this direction?

Unless there has been some discovery that I am unaware of, electrons moving from one energy state to another is not the same as an electron moving down a wire. No magnetic field will be produced when "moving" from one state to another.
If something like what you describe we're to happen, each electron's magnetic field change would be in its own direction, so there would not be a coherent field to capture.

Your question is not clear. But you should be confidant that every possible way to improve their performance has been considered.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
