Groundbreaking new solar cell solves vexing high temperature issue

In our quest to replace fossil fuels with solar power, we have to first fix the solar cell , which typically stops working at temperatures above 100°C. Luckily, researchers at TU Wien may have just discovered a way to solve this issue with a solar cell that can work at 400°C. Based on the doctoral research of Georg Brunauer, the new solar cell can work at temperatures of 400°C, which makes it possible for the cell to store solar energy . Traditional solar cells need batteries or supercapacitors to store the energy from sunlight, and often convert that energy directly into electricity instead of storing it, which requires high temperatures. Related: Paper-thin solar cells could provide power for 1.3 billion people Brunaeur’s system combines photovoltaics and electrochemical storage to store UV light chemically. It’s reminiscient of the way plants store energy from the sunli...
