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.
The greatest silicon solar cell achieved a 26.7 per cent efficiency on a lab scale, whereas today’s standard silicon solar cell panels run at roughly 22 per cent efficiency. As a result, many current solar research programmes are devoted to identifying and developing more effective sunlight conductors.
Silicon now accounts for more than 90% of the solar cell industry. Silicon is a cost-effective material with high energy efficiency. That is why it is frequently employed as a semiconductor material in first solar cells. Aside from that, it possesses strong photoconductivity, corrosion resistance, and long-term durability.
More than 80% of manufactured solar cells are based on a crystalline silicon (single-crystalline or multicrystalline) substrate. The value stream of the photovoltaic industry is shown in Fig. 51.2 [51.2]. PV silicon value stream (after [51.2])
Pure crystalline silicon, which has been used as an electrical component for decades, is the basic component of a conventional solar cell. Because silicon solar technology gained traction in the 1950s, silicon solar panels are commonly referred to as “first-generation” panels. Silicon now accounts for more than 90% of the solar cell industry.
That is why it is frequently employed as a semiconductor material in first solar cells. Aside from that, it possesses strong photoconductivity, corrosion resistance, and long-term durability. Because silicon is plentiful in nature, there is practically no scarcity of raw materials for making silicon crystals.
