Lead-halide perovskites with enhanced luminescence and stability

Lead halide perovskites are materials that emit light with a range of colors, but also suffer from poor moisture stability. Scientists in China demonstrated a new synthetic technique that can enable perovskites to emit bright ...

Lead halide perovskites are not ferroelectric

In a solar cell, when the sunlight impacts the material, a charge is generated. Specifically, this charge corresponds to an electron-hole pair, where an electron is excited to the conduction band, leaving a hole in the valence ...
