A photovoltaic cell produces electricity primarily because photons absorbed in a semiconductor p-n junction:

Free electron-hole pairs that the built-in electric field separates into a usable current Heat the junction until thermoelectric voltage appears across the metal contacts Spin the module frame so magnetic flux cuts the interconnect ribbons Store charge chemically in the encapsulant the way a battery stores ions

Correct Answer:

Free electron-hole pairs that the built-in electric field separates into a usable current
