This document discusses photovoltaic (PV) cells, explaining that they convert solar energy to electrical energy through the photovoltaic effect using doped silicon. PV cells are used as alternative power sources in satellites, in solar panels to generate electricity, and placed over river channels to prevent water evaporation.
