Self-assembling particles brighten future of LED lighting

Princeton engineering researchers have illuminated a path forward for LED technologies by refining the manufacturing of light sources made with crystalline substances known as perovskites, a more efficient and potentially lower-cost alternative to materials used in LEDs found on store shelves.

The researchers developed a technique in which nanoscale perovskite particles self-assemble to produce more efficient, stable and durable perovskite-based LEDs. The advance could speed the use of perovskite technologies in commercial applications such as lighting, lasers and television and computer screens.

Perovskites exhibit a number of intriguing properties—they can be superconductive or semiconductive, depending on their structure—that make them promising materials for use in electrical devices. In recent years, they have been touted as a potential replacement for silicon in solar panels: cheaper to manufacture while offering equal efficiency as some silicon-based solar cells.
