All the electromagnetic waves emitted by the Sun.
antireflection coating ![click to hear](/images/speaker.jpg)
Coating product that is deposited on the negative region to reduce light reflection and optimize solar radiation absorption.
negative region ![click to hear](/images/speaker.jpg)
Layer of semiconductive material (silicon) to which phosphorous is added to release electrons.
positive region ![click to hear](/images/speaker.jpg)
Layer of semiconductive material (silicon) to which boron is added to produce a layer with insufficient electrons.
positive/negative junction ![click to hear](/images/speaker.jpg)
Contact area in which electrons are exchanged between two layers to create an electric current; radiation moves the charges between these regions to create voltage.
