Lightselectricity

Lightselectricity is a field focused on the interactions between light and electrical energy, encompassing the generation, manipulation, and conversion of electricity using optical signals, as well as light-based control of electronic processes. The term integrates concepts from photovoltaics, photonics, and electronics to describe how light can create, transfer, or regulate electrical power and how electrical systems can respond to or emit light.

Key topics within lightselectricity include the photoelectric effect and photovoltaic conversion, photoconductivity, and electro-optic or all-optical control of electronic signals. Materials of interest range from traditional semiconductors such as silicon and gallium arsenide to emerging systems like perovskites, organic photovoltaics, and quantum dots. Devices studied or developed in this area include solar cells, photodetectors, light-emitting diodes, laser diodes, and electro-optic modulators, as well as integrated optoelectronic circuits that combine photonic and electronic components on a single platform.

Applications of lightselectricity span energy, communication, and sensing. Solar energy systems convert light to electricity for power generation; photodetectors enable optical communications and sensing networks; LEDs and laser diodes provide light sources for displays, illumination, and data transmission; and optoelectronic integration aims to improve speed, efficiency, and form factor in electronic devices. Challenges in the field include improving energy conversion efficiency, material stability, device longevity, manufacturing cost, and integration with existing electrical grids and infrastructures. Lightselectricity remains an active area of research and development with potential impacts across energy, information technology, and consumer electronics.
