Half of the Joule heat ends up directly in the cold side, and half of the heat ends up in the hot side. The equation is created in such a way that it cares only about one side, therefore we only consider half of the total Joule heat. We have the Peltier heat which is kind of the heat that can be used for cooling, and the rest of the equation (terms with the minus sign) are working against this heat.
@@CuriousScientist one other question sir, the heat Qc is the hot side's heat of the battery or the peltier device ? it's moving form the battery's hot surface to the cold side of the TEC or it's moving from the hot side of the TEC to his cold side ? thank you for this video it helps so much.
@@CuriousScientist i am sorry if it wasnt clear i just want to know what is Qc, its the heat transfered from what to what. thank you for your patience sir.
It's a mixture of my university lecture notes and some lab reports I made at that time. But you can look up any solid state/condensed matter physics text book, you should find the same.
sir why you devided the Joul heat by 2 ?

I am sorry but read your question again, it doesn't make any sense. Please rephrase it, so I can understand what you want to ask.

Qc is the cooling power of the Peltier. The amount of heat pumped from the cold side to the hot side.
can you put references please

Chemical potential = Fermi level
Yes!
