Solar Photovoltaics
Light to electricity conversion
Solar PV uses semiconductor junctions where light excites electrons creating current collected by contacts.

Inputs
Sunlight hitting semiconductor layers in PV cells.
Process
Photons free electrons; junction creates voltage; wiring carries DC power to an inverter.
Outputs
Usable AC electricity after inversion and grid-tie or storage.
