Silicon is employed as first material to manufacture Solar cells but its disadvantages are high cost and lower efficiency. Thin-film solar cells are known as second generation of the solar cell fabrication technologies to produce power electrical energy.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
Coping with the challenges: Although, crystalline solar cells are used widely in the market today, issues associated with silicon are preventing the demand of the solar energy to increase. Though single crystalline silicon is very efficient relative to other kinds of the solar cells, the cost factor overrules its advantage with the efficiency.
Commercially, the efficiency for mono-crystalline silicon solar cells is in the range of 16–18% (Outlook, 2018). Together with multi-crystalline cells, crystalline silicon-based cells are used in the largest quantity for standard module production, representing about 90% of the world's total PV cell production in 2008 (Outlook, 2018).
Waste crystalline-silicon solar cells have great resource value . Recyclable parts of crystalline-silicon solar cells include silicon, aluminium frame, tempered glass and metals such as silver, aluminium and copper. Some scholars have studied the leaching toxicity of solar panels and found that lead in cells has a high leaching toxicity .
The main advantage of monocrystalline silicon cells is the high efficiency that results from a high-purity and defect-free microstructure. Currently, the Cz method has evolved into a highly sophisticated technique, governed by multiple parameters. This complexity adds further challenges in understanding and enhancing the current methodology.
