One of the thing I understand from this article is that there are some preserved energy phonon in the semiconductor lattice. Typically, this energy is stored somewhat like heat. In order to reach 200% efficiency, they have to tap into this stored phonon to generate photons. Now the question is, how do you get the phonon?
In the experiment condition they also heat up the LED to 135 degree C. This is very close to the maximum junction temperature of that LED, and thus they cannot put more bias voltage to it. That said, if the application is that we need to heat up the LED in order to get this 200% efficiency, we also need to consider how much heat that we have to submit to the LED for this to happen. Hmmm.. but, wait, I got a Core i7 that would be perfect candidate for the heating source. Problem solved!
