solar radiation click to hear : solar radiation

All the electromagnetic waves emitted by the Sun.

antireflection coating click to hear : antireflection coating

Coating product that is deposited on the negative region to reduce light reflection and optimize solar radiation absorption.

negative region click to hear : negative region

Layer of semiconductive material (silicon) to which phosphorous is added to release electrons.

positive region click to hear : positive region

Layer of semiconductive material (silicon) to which boron is added to produce a layer with insufficient electrons.

positive/negative junction click to hear : positive/negative junction

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.

positive contact click to hear : positive contact

Metal element that ensures that the electric current flows through the circuit to which it is attached.

negative contact click to hear : negative contact

Metal element that ensures that the electric current flows through the circuit to which it is attached.

metallic contact grid click to hear : metallic contact grid

Metal grille that collects the electric current being generated.
