    Hello everyone!
    I have a thesis to design a temperature stabilizing(controlling) system for solar cells.I need to use 12V Peltier battery and a simple pc fan.Any further help is appreciated.

    It is also unclear what you are trying to do.

    Peltier battery? Is that a Peltier cooler in reverse?

    If so, how are you going to ensure enough heat flow through the cooler to run a fan? Remember it's the flow of heat that powers the battery. A simple difference in temperature won't do since both sides of the battery will soon be at the same temperature. You need a hot side that stays hot and a cool side that stays cool.

    The electronics are simple. The battery. Possibly a temperature sensor/switch. A fan. Use multiple batteries in series or parallel to get the fan's voltage and current.

    The hard part will be the heat flow equations. For a non-thesis some simple equations would get you in the ballpark, but properly done these will be difficult.
