The field and the foil work collectively to mirror and take in daylight, trapping the warmth contained in the oven. 

The glass or plexiglass retains the warmth trapped inside (with out blocking the daylight), whereas the insulation or cotton padding prevents warmth loss. 

Moreover, some photo voltaic ovens additionally use reflectors to direct extra daylight into the oven.

Completely different designs

There’s all kinds of designs for photo voltaic ovens.

Probably the most simple design consists of a reflective materials (panel) put collectively in a method that directs the daylight to a goal (the pan/meals). You’ll be able to name it the “sluggish cooker” of photo voltaic ovens, because it doesn’t entice the warmth “inside” the oven to hurry up the cooking course of.

Nonetheless, it may possibly create sufficient warmth to prepare dinner meals for those who’re prepared to attend lengthy sufficient.

That is what it appears to be like like:
