By pointing their device toward space, whose temperature approaches mere degrees from absolute zero, the group was able to find a great enough temperature difference to generate power through an early design.

“The amount of power that we can generate with this experiment, at the moment, is far below what the theoretical limit is,” said Masashi Ono, another author on the paper.

The group found that their negative illumination diode generated about 64 nanowatts per square meter, a tiny amount of electricity, but an important proof of concept, that the authors can improve on by enhancing the quantum optoelectronic properties of the materials they use.

Calculations made after the diode created electricity showed that, when atmospheric effects are taken into consideration, the current device can theoretically generate almost 4 watts per square meter, roughly one million times what the group’s device generated and enough to help power machinery that is required to run at night.

By comparison, today’s solar panels generate 100 to 200 watts per square meter.

While the results show promise for ground-based devices directed to the sky, Fan said the same principle could be used to recover waste heat from machines. For now, he and his group are focusing on improving their device’s performance.
