Is there any evidence to suggest that stronger consumer grade magnets like the one in this magnetic phone holder can negatively impact the efficacy of consumer grade solar cells like the one in this TV remote?

It's likely that these items could come into close contact, and while I understand that these types of magnets don't really impact lithium batteries (lots of people have asked this question), I'm not sure about solar cells.

All I can think is that you might get some splitting of electron levels that might make it ever so slightly less efficient (I'm talking a parts-per-billion change if any). Static magnetic fields don't really have much of an effect on things that aren't themselves relying on magnetic phenomena. \$\endgroup\$

    \$\begingroup\$ Sounds more like a weak excuse for the solar cell having insufficient ability to charge the battery under typical use conditions. \$\endgroup\$

It would not affect it electrically. A static magnetic field from a consumer grade magnet isn't strong enough to affect diodes or transistors. If there were any mechanical issues that could be a problem but beyond the scope of this site.

You'd possibly get some resistance increase due to the hall effect, but that's all I can think of. It would probably not be enough to be easily detected.
