The team, which also includes Brian Watson and Adam Printz, has thus built an analogous scaffold for a compound solar cell based on cells filled with perovskite that survive fracture testing well with little loss of solar conversion efficiency. Each cell in the vast honeycomb of perovskite microcells is just 500 micrometers across. "The scaffold is made of an inexpensive epoxy resin widely used in the microelectronics industry," team member Nicholas Rolston explains. "It's resilient to mechanical stresses and thus far more resistant to fracture."
