The first commercial PV solar product was nah just in 1909.
See story above, and original article in Modern Electrics magazine in 1909:

EDIT
Since people didn’t read past the headline, the article is about a startup company in 1905 that developed a commercial electrical solar panel by 1909 and was worth 160 million in today’s money.
In 1909, the inventor of the solar panel was kidnapped and ordered by his kidnappers to destroy all information about this solar panel. He was eventually released, although he did not destroy the solar panel or his documentation, he did shut down his company.
So this is a pretty fascinating development considering that at this time period we actually did have early production electric cars that were manufactured in larger quantities than gas vehicles, and now we learn that solar panels were commercially available, at least for a short time.
And the solar panels could generate a fair amount of electricity:
500 volts per 10 square ft, and a smaller demonstration panel that was 3 ft x 4 ft could generate 60 watts of power (10 volts @6 amps).
Additionally, the panels were designed to charge a battery backup system.

Wait… then what am I thinking of? I’m sure this effect is used somewhere

The whole internet is AI bots bro. You’re the only real human here.
If I was a human though, I would be Kiwi. Kia ora!
Yeah, I think that’s what I was thinking of.
You are thinking of a thermo-electric cooler (TEC) or peltier cooler. They actually are used on smaller wine fridges but not full sized fridges. They are light-weight, electrically efficient, and reliable. They were also used in the early days of CPU overclocking.
