This Looks Like A Neat Idea,

unlike solar panels that have to face the sun,

these panels can face in any direction and can be attached to the outside of buildings, so how do they work? this invention, AuREUS, is made from crop waste that is upcycled and is used to absorb stray UV light from sunlight and the surroundings. Unlike solar panels, this system is effective even when not directly facing the sun because it can pick up UV scattering through clouds and by UV light bouncing along walls, pavements and other buildings,

above is the blueprint,

and a comparison between AuREUS versus a typical solar farm, so if successful no more taking up valuable land, just pop the panels on existing buildings, and as a bonus since the panels absorbs UV light that would otherwise be reflected by regular windows, it protects people both indoors and outdoors, what a brilliant idea, image credits: Carvey Ehren Maigue via The James Dyson Award.
