Stanford toughens up cheap solar cells by mimicking insect eyes

Their solution involves encapsulating perovskite microcells in a hexagon-shaped epoxy resin scaffold that measures 0.02 inches wide. They then put hundreds of those together like a honeycomb to mimic the compound eye of a fly. The study’s co-lead author Nicholas Rolston says the scaffold wall protects the fragile minerals, especially since epoxy resin is “resilient …
