According to the most
recent data from Bloomberg New
Energy Finance (BNEF) wind and solar energy are already cheaper
than traditional alternatives in two-thirds of the world, and is
expected to be the cheapest option everywhere by 2030.
One of the major drawbacks of solar energy is that it can only produce energy during the day, but new research (Nighttime Photovoltaic Cells - Electrical Power Generation by Optically Coupling with Deep Space) published in the journal ACS Photonics, suggests that solar panels can be built in a way that allows them to generate energy at night as well.
The basic concept is that
energy can be generated through the process of the heat leaving the
panels and cooling down at night, this is known as radiative
Jeremy Munday, a professor in the Department of Electrical and Computer Engineering at UC Davis, is one of the researchers who are working on prototype versions of this technology.
The ACS Photonics study suggests that if solar farms were to implement this technology, they could produce up to 50 watts of power per square meter, which would boost energy production by about 12%.
