Excerpt: "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."
