Optoelectronic materials

Optoelectronic materials are materials that can generate, detect, transmit, absorb, or control light through interactions between photons and electrical charge carriers. They form the basis of technologies that convert electrical signals into optical signals, or optical signals into electrical signals. Common examples include semiconductors, perovskites, quantum dots, organic compounds, and two-dimensional materials. They are used in solar cells, LEDs, displays, photodetectors, image sensors, lasers, optical communications, and other electronic systems. Their performance depends on properties such as bandgap, charge mobility, light absorption, emission efficiency, stability, and compatibility with manufacturing processes.
