As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.
