Solar records are broken left and right. We can't cover them all, of course, but try to cover the big ones. Recently, researchers ar Empa, the Swiss Federal Laboratories for Materials Science and Technology, set a pretty big one. They increased the solar cell efficiency record of flexible solar cells made of copper indium gallium (di)selenide (aka CIGS) from 17.6% to 18.7%, a pretty significant increase
