Squeezing a rock-star material could make it stable enough for solar cells

Scientists at SLAC National Accelerator Laboratory and Stanford University discovered that squeezing a promising lead halide material in a diamond anvil cell (left) produces a so-called “black perovskite” (right) that’s stable enough for solar power applications.
