Researchers have found a new way to improve a key element of thermophotovoltaic systems, which convert heat into electricity ... maximizes energy conversion and allows for higher efficiencies ...

A research team has achieved significant breakthroughs in harnessing low-grade heat sources (100 °C) for efficient energy conversion. A team of researchers, jointly led by Professor Hyun-Wook Lee ...

This means that most heat energy conversion is based on high temperature, and low-grade heat conversion devices will never be able to achieve high conversion efficiencies. This first prototype can ...
