Simple process surprisingly perovskite or into LED future production materials

American researchers have found that perovskites can achieve high-brightness LEDs at lower cost and simpler processes. The perovskite used to make LEDs is called organometallic halogenated perovskites and is a mixture of lead, carbon-based ions and halide ions. This material is well soluble in common solvents and polymerized into perovskite crystals after drying. The cost of the process is very low and the process is very simple.

Perovskite LEDs do not require the high temperature heating or high vacuum processes required for silicon-based LEDs. “It’s amazing how such a simple process can still produce semiconductor materials with very good properties – without the complex purification processes required for traditional semiconductor materials,” said Richard Flander, a researcher at the University of Cambridge.
