It is only possible to do that if the photons are sent somewhere that is colder than the device.

No, I'm saying it can't impart all of its energy, and the more energy the other body has the less energy it can impart. i.e. it's exactly Carnot efficiency.

Perhaps what you don't realize is that Carnot efficiency doesn't represent lost energy. It represents heat energy than can not be converted to another form, and remains in the source.

Where are you deriving this from. What force prevents me shining a light towards a hot object.
