Why are silicon solar cells a popular choice?

Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.

What is a silicon solar cell?

A solar cell in its most fundamental form consists of a semiconductor light absorber with a specific energy band gap plus electron- and hole-selective contacts for charge carrier separation and extraction. Silicon solar cells have the advantage of using a photoactive absorber material that is abundant, stable, nontoxic, and well understood.

How is silica used in solar cells?

Silica is utilized to create metallurgical grade silicon (MG-Si), which is subsequently refined and purified through a number of phases to create high-purity silicon which can be utilized in the solar cells. The silicon is first extracted from beach sand. Sand mining is only carried out on a few numbers of beaches throughout the globe.

How does a photovoltaic cell produce electricity?
