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 "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.
Over the years, as a result of continuous research and development (R&D), the efficiency of PV cells has improved from ~1% in the early days of PV to 40% for multijunction cells [4, 5]. The efficiency of commercially dominant single-junction cell technology is ~24%, which is close to the maximum theoretical efficiency (Shockley–Queisser limit) of 33% [ 6 ].
