Solar Photovoltaic Cell Basics. When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the …
In solar cells made of silicon, radiative recombination seldom dominates and is extremely slow. Within the silicon energy bandgap, impurity atoms or defects present inside the solar cell bulk produce sub-bandgap levels, and if the electron enters these states followed by recombination with a hole, trap-assisted or Shockley–Read–Hall (SRH ...
