What are optoelectronic devices? Give the names of such major devices.

Explanation

Optoelectronic junction is the device in which the photons (photo excitation) generates the carriers due to the photons.
Optoelectronic device are as follows:
(1) Photodiodes used for detecting optical signal (photodetectors).
(2) Light emitting diodes (LED) which convert electrical energy into light.
(3) Photovoltaic devices which convert optical radiation into electricity (solar cell).
