Move over solar pannels, introducing spray-on solar cells

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture.

Solar Panel Hybrid is Cheap and Super Efficient

Solar Power

Solar cells are inefficient, it’s a sad fact. With todays technology they boast about a 10-15% efficiency, compare that to todays gas engine at roughly 20-25% and you can see it’s not quite up to par. Well that could all change very soon thanks to a new method for transferring energy from organic to inorganic semiconductors. This could boost the efficiency of widely used inorganic solar cells to as close as 100% efficiency as they can get.
