Pyroelectric effect hm...

[atom888]

The term defines a material possess electrical potential under different in temperature. That means we can harness power. That means we can make engine with a near 100% efficiency.

No the efficiency of pyroelectric energy conversion is still well less than 100%. Was that your point?

use the waste heat in the condenser before it go out to the reservoir . Of course there still efficiency in the process but we getting some more worked out of the whole thing.

What condenser? And how would you use the photoelectric effect on condenser heat? It requires photons - energetic ones, at that. You can't just point a solar panel at a warm object and expect it to generate a bunch of electricity from the handful of far infrared photons it receives.
