Stanford toughens up cheap solar cells by mimicking insect eyes
While silicon solar panels are already providing electricity for a lot of homes and buildings, it doesn't mean researchers have stopped looking for better and cheaper alternatives. Case in point, a team of Stanford scientists working to make a cheaper photovoltaic mineral called perovskite a viable option for people who want to shift to solar. Perovskites are as efficient as silicon solar cells when it comes to converting sunlight into energy, but they're fragile and can deteriorate easily when exposed to the elements. The team had to find a way to make them more durable -- and they've found inspiration in the compound eyes of insects.
