Can infrared photons also eject electrons in 'photoelectric effect'?

[QUOTE="royp, post: 6418120, member: 261943"] Hello, I have this question whether it will be possible to generate electricity by heating up a suitable metal (conductor). We know from the photoelectric effect that high energy photons (of visible light; probably with frequency closer to that of violet) can knock off the outer electrons from some material in enough numbers to create a significant electric current - as is evident from solar panels. Are there suitable metals/materials having outer electrons quite loosely bonded to the atoms in such a way that the electrons can be ejected from them by simply heating these materials sufficiently - so much so that it will produce useful electric current? This question is prompted by a '[B]stove fan'[/B] I recently purchased. There is a motor at the back of the fan and it appears that the bottom of the fan, when placed above the stove and heated, supplies '[B]power[/B]' to the motor. I will be grateful for your explanations. Thanks in advance. [/QUOTE]
