Peltier elements are semiconductor junctions that produce cooling when DC voltage is applied across them, a phenomenon called the Peltier effect discovered by Jean Charles Athanase Peltier in 1834.

Evidence Quote
“This is a Peltier element... when I apply a DC voltage across these two wires, the plate becomes cold. This is called thermoelectric cooling, and it's happening thanks to the Peltier effect.”
