The Creation of a Solar Panel That Works at Night Surprised a Series of Researchers

Professor Jeremy Munday from the University of California (Davis, USA) has created a “solar” panel that can generate power even when there is no trace of light, such as at night. This panel operates similarly to conventional solar panels, except the process is as if it were reversed.

How Munday’s Panel Works

Basically, conventional solar panels convert heat generated from capturing sunlight into energy. This means that at night, they are practically useless. The panel created by Munday uses the same principle to generate energy from heat, but utilizes thermoelectric cells that can be heated even in the absence of light.

Thermoelectric cells emit heat as infrared light, using an approach similar to the solar panels we know, but functioning the opposite way. Munday’s panel requires fossil fuels to operate, but these would only be supplied through industrial processes that would cease to waste energy. Thus, generating extra energy would be a way to offset these carbon emissions.

In this initial prototype stage, the invention is capable of generating 50 watts of electricity per square meter. This represents only 25% of the capacity of a conventional solar panel operating during the day. Still, this efficiency is better than wasting the full energy potential of burning fossil fuels in industrial processes.
