AFAIK, no one has tried to build a Peltier cell paired with a heat pump. I am not an expert, but I would imagine that it's a path that could bring higher efficiencies. Thoughts?

It seems to me that if you have a heat pump, you don't need the Peltier anymore.

The heat pump is already so efficient that, I assume, adding something less efficient just makes it worse.

Also not an expert, but I’m struggling to find a combination where one of those couldn’t be replaced with a passive thermoconductive element. It’s hard to beat the efficiency of “free”.

It would be more efficient to just make the heat pump slightly more capable of cooling to reach the same total performance

It's one of those cases where you can chase a very small relative gain by adding a lot of complexity.

Like horsepower.
