In the future, windows and solar panels could be made from one of the best — and cheapest — construction materials known to man: wood. Researchers at the KTH Royal Institute of Technology in Stockholm have developed a transparent wood that’s suitable for mass production. It was presented in March 2016. Lars Berglund, professor at the Wallenberg Wood Science Centre in KTH, says that while optically transparent wood had been developed in microscopic samples during the study of wood anatomy, the new KTH project introduces a way to use the material on a large scale. “Transparent wood is good for solar cells, since it’s a low cost, readily available, renewable resource”, Berglund says. “This becomes particularly important when it comes to covering big surfaces with solar cells.”
