The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).
Technologically, the main challenge for the photovoltaic industry is improving PV module energy conversion efficiencies. Therefore, a variety of techniques have been tested, applied and deployed on PV and PV/T systems. Combined methods have also been a crucial impact toward efficiency improvement endeavors.
