Awesome! But did they solve the perovskite cell longevity problem. Those supposedly degrade below usefulness in several years vs. ~20 years for silicone cells. Anyway - this is an important feat even if in concept form. But how did they reach the 10kWh figure is kinda iffy.
The company that brought the fastest-charging electric car battery is at it again with a perovskite photovoltaic sunroof for its electric SUV. When integrated into the hood and doors as well, the solar panel tech generates 10 kWh per day.
