Why something like picrel won't work aside >inb4 he laws of thermodinamics?
I think it should at least work to maintain itself.

It cant maintain itself because some of the energy leaves the system (the light that goes out away from the cell)

solar panel 60% efficient. light 98% efficient. put 5 units of energy into light bulb. lose 2%. solar panel gets hit my light lose 60%. 60% of power gets lost by light bulb additional 2% on and on and on till there is no energy left.

What if it was completely surrounded by a mirror-like substance that does not absorb any energy?

nothing in this world is 100% efficient and has losses, remember a lot of this energy just simply heats matter and isn't reflected or conserved in any way

What if both were 100% efficient?

then it still would never be able to power anything. even if it was magic and 100% efficient, it would still be useless
>dude what if the very nature of reality was different???

even if everything was perfect with 100% efficiency, you still have massive losses because only a small fraction sent by the bulb reaches the panel

then build a mirrored box around the device to capture all of the photons and insulate it with a vacuum. theoretically that should work.

nope. mirrors do not reflect light 100%. the glass is scattering and absorbing some, even the mirror layer itself absorbs some, reducing the light which actually gets reflected.
