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).

But due to the lower cost of multi-crystalline (mc) silicon, in the 1980s mc silicon wafers rose as a potential candidate to replace single-crystalline (sc) ones. On the other hand, their lower metallurgical quality due to the presence of defects in the form of grain boundaries has precluded achieving efficiencies similar to those of Cz, so that both technologies shared a …
Silicon is one of the most abundant elements on earth, perfectly stable and nontoxic. The so-called first-generation crystalline silicon PV cells are the commercial PV modules basis acting as the semiconductor material with a thickness of about 200 μm. Two types of cells are distinguished as illustrated by Fig. 4.3.The mono-crystalline silicon cells have a perfectly arranged crystalline ...
Conventional solar panels use crystalline silicon (Si), which must be produced from highly pure silicon, known as metallurgical grade. Metallurgical grade Si (MG-Si) is primarily sourced from quartz (silicon dioxide) rocks, though it needs a lot of processing to go from rock to silicon. To extract silicon, the oxygen in silicon dioxide is removed by mixing it with carbon and heating it …
In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing). We briefly describe the different silicon grades, and we compare the two main crystallization mechanisms for silicon ingot production (i.e., the monocrystalline Czochralski process and ...
Effective surface passivation is crucial for improving the performance of crystalline silicon solar cells. Wang et al. develop a sulfurization strategy that reduces the interfacial states and induces a surface electrical field at the same time. The approach significantly enhances the hole selectivity and, thus, the performance of solar cells.
