That’s no joke,
YES
according to Jeremy Munday,

CAN SOLAR CELL WORKS AT NIGHT
Researchers at Stanford published
a paper Stating that thermoelectric
generator which radiates heat to the
sky can generate electricity
ANTI SOLAR
PANEL.

22.  according to a concept paper by Munday and
graduate student Tristan Deppe. January
2020.
 It can generate ¼ th of power what is
generated by solar panel in day time.

25. ANTI SOLAR PANEL
• Facing warm objects to the
sky so that they radiate
heat, -----given the fact that
space is very cold.

Thermoradiative cell at night
The cell emits thermal
radiation in the infrared into
space.
heat source 300K

27. THERMORADIATIVE (TR) PV OPERATION
emission reduces the carrier
concentration below thermal
equilibrium

COMPARISON ON PV AND TR

29. ANTI SOLAR PANEL
photovoltaic (quadrant 1)
Thermoradiative (quadrant 3)
negative voltage and negative current
generate positive power across an
external load
29

30. Difference between a TR PV cell and a conventional
PV cell is that,
 The current flows in the opposite direction
 The sign of the voltage is also reversed;
therefore, both scenarios generate usable power.

WORKING MODEL
Munday and his team are currently working on
developing prototypes to see how well they can
make this concept work.

 Currently Researchers are working
on developing it with Mercury
instead of Using Silicon or any
alloys

37.  we can devise a system
that can generate clean
