The market for photovoltaic (PV) systems has long been dominated by silicon solar cells because of their high efficiency and remarkable stability, which have been achieved through consistent research and development in the technology.
Silicon is positioned as the leading technology in the PV market due to this factor. It has been shown that after 25 years, silicon photovoltaic cells can retain more than 80 % of their original power conversion efficiency , meeting the standard stability tests for PV technologies.
Another intrinsic property of photovoltaic solar cell materials that significantly affects efficiency is the bandgap. Silicon cells are limited by their bandgap, which restricts their responsiveness to the broad spectrum of solar energy. This limitation also results in excess thermal energy from non-useable photons, impacting overall performance.
