Theorists propose new approach to electroluminescent cooling that works like inverted solar photovoltaic cells

In a study appearing in PRX Energy, researchers propose a way to improve the performance of electroluminescent cooling by using multilayer semiconductors. The approach, called a multijunction configuration, is already used in some special photovoltaic solar cells. Electroluminescence is the phenomenon behind how LEDs work. It involves adding charge carriers, either electrons or holes, to a semiconductor. This changes the semiconductor's properties, including how it conducts or insulates against the movement of electrical charges. In an LED, the charge carriers cause the semiconductor to emit photons of light. This emission can require more energy than is present in the semiconductor. If this is the case, the excess energy to make light comes from heat around the semiconductor. The result—a semiconductor can cool down by emitting light.

As a Person who is Not a Scientist but Likes Science, i can also confirm that this is, indeed, funny.

Hi I'm

Math enjoyers do not DNI. If you like math you are required to interact with me.

I just realized...

THE DIVISION SYMBOL (➗️) LOOKS LIKE A FRACTION

• <---- the numerator

-- <---- the line separating the numerator and denominator

• <---- the denominator

The numbers are just replaced with dots!
