But if you find yourself, in the not-so-distant future, adding new-and-improved solar panels to your roof, they may well contain a perovskite layer. If they do, it will be these…

Physical Benefits

Of the four new articles online on our website, three happen, purely by accident, to be on physics research. The three are very different, and yet each is an illustration of the ways that basic physics research changes our world – in small and large, practical and enlightening ways. And each is situated at a…

December’s calendar photograph is a battery of five solar cells that also stores electricity in series. The cells were invented and developed at the Weizmann Institute in the late 1970s. These not only converted sunlight into electricity, but also could store some of that energy using a battery-type setup with electrodes in a chemical solution,…
