#387 Solar cells and LEDs

 Some more about light and semiconductor diodes….


In terms of interactions with light, semiconductor diodes represent two distinct, very different classes of devices. Some of them are converting light into electricity and those are obviously solar cells working of the principles of the photovoltaic effect and photodiodes working as light detectors.


The devices in the second group work in the exactly opposite direction and convert electricity into light with light emitting diodes, or LEDs in short, being a prime example of light emitting device. Here, the effect of photoluminescence is a foundation of the device operation.
