Photovoltaic cells, which are essential for the functioning of a solar energy system, are made using silicon. Here's why: Silicon is a semiconductor, which has properties that fall between those of conductors and insulators.
Silicon is used in solar cells because it is a semiconductor with properties that fall between conductors and insulators and has an electrical property that makes it conductive in one direction and insulating in the other. Additionally, silicon solar cells have recorded an efficiency of over 20% due to their photosensitivity.

Silicon has very high photoconductivity that makes it a popular choice for photovoltaic cells. Silicon's silicon dioxide layer absorbs energy when it is exposed to light and converts the photons from incident sunlight into free electrons that are then able to produce electricity. 9.
