The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.
The development of silicon-based photovoltaic (PV) cells began with the discovery of the photovoltaic effect by Alexandre-Edmond Becquerel in 1839.
Front and Back Contact Formation Technically, a silicon wafer is a solar cell when the p–n junction is formed, but it only becomes functional after metallisation. The metal contacts play a key role in the production of highly efficient and cost-effective crystalline Si PV cells.
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.
Improvement of the efficiency of the furnace in terms of its design. The recycling of PV modules for silicon production can also contribute to reducing energy consumption and thus CO 2 emissions, depending on how much energy is required to process the recycled silicon material to the appropriate quality for wafers [2, 9].
