Scientists have created a material that generates energy from temperature changes, hinting at a future where solar power no longer needs panels
by Anke
April 23, 2026Excerpt: "The 'Honeycomb' barrier to break energy loss barriers
"Converting heat into electricity is a rising trend in the engineering world. However, #thermoelectrics have always been considered too inefficient for wide-scale use, until now.
"Scientists from the Seoul National University (#SNU) College of Engineering created a new material with high-performance #thermoelectric properties.
"You can review their study 'Facile and scalable strategy for fabricating dense bulk Ag2Se as a high-performance thermoelectric material,' published in Advanced Composites and Hybrid Materials.
"The team’s design is based on #SilverSelenide (#Ag2Se) and operates on the #SeebeckEffect, producing voltage from temperature gradients.
"Blocking heat while boosting the power factor"Ag2Se was scaled into nanoflakes and arranged in a honeycomb-like layout.
"Heat-carrying vibrations (#phonons) are scattered in the structure, preventing the temperature from leveling across the material.
"The material was 'doped' with #silver, which boosted the power factor by 300%, enabling electron flow despite the thermal barrier.
"This breakthrough in thermoelectric materials effectively renders the need for panels unnecessary.
"The highly efficient, thin, and flexible film has a series of application possibilities. Building integration enables solar power production from heat during the day and energy harvesting as the building cools at night.
"Flexible thermoelectric patches can power IoT devices, eliminating the use of batteries. Using the material at data centers creates a circular energy economy within digital infrastructure itself."

#Materials with enhanced #thermal #conductivity are critical for the development of advanced devices to support applications in #communications, clean energy and #aerospace. But in order to #engineer materials with this property, scientists need to understand how #phonons, or #quantum units of the vibration of atoms, behave in a particular substance.

Atoms in #crystalline solids sometimes vibrate in unison, giving rise to emergent phenomena known as #phonons. Because these collective vibrations set the pace for how heat and energy move through materials, they play a central role in devices that capture or emit light, like solar cells and LEDs.

[dying to know what the consensus ended up being on this radical theory (pub 23 Jul 2018). guess I'l do some hunting; tips appreciated]
trio of #ColumbiaUni physicists is making waves with a new theory about #phonons—they suggest they might have negative mass, and because of that, have negative gravity. Angelo Esposito, Rafael Krichevsky and Alberto Nicolis have written a paper to support their theory, including the math, and uploaded it to the xrXiv preprint server. -
Cool.
"You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science."
