Birds have inspired human flight for centuries, but Shabnam Raayai thinks they can also offer lessons in reducing energy consumption. A fellow at the Rowland Institute at Harvard, Raayai works to ...

There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too. While serving as a visiting ...

Perovskite solar cells have surged from laboratory curiosities to serious contenders against silicon in barely a decade, yet the physics behind their remarkable energy harvesting has remained partly ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching ...
