The crystallization of silicon is a crucial step in the PV manufacturing process. Being the first step in shaping the silicon wafers, it impacts the subsequent manufacturing steps and overall efficiency potential for the product. The crystallization of silicon is our core expertise.
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

NPG Asia Materials 2, 96–102 (2010) Cite this article Crystalline silicon photovoltaic (PV) cells are used in the largest quantity of all types of solar cells on the market, representing about 90% of the world total PV cell production in 2008. Crystalline silicon solar cells are also expected to have a primary role in the future PV market.
Production technologies such as silver-paste screen printing and firing for contact formation are therefore needed to lower the cost and increase the volume of production for crystalline silicon solar cells.
In the ten years since the first demonstration, the efficiency of crystalline silicon cells was improved to around 15%, and were sufficiently efficient to be used as electrical power sources for spacecraft, special terrestrial applications such as lighthouses, and consumer products such as electronic calculators.
There are generally three industries related to crystalline silicon solar cell and module production: metallurgical and chemical plants for raw material silicon production, monocrystalline and polycrystalline ingot fabrication and wafer fabrication by multi-wire saw, and solar cell and module production.
In order to make multi-crystalline silicon cells, various methods exist: DSS is the most common method, spearheaded by machinery from renowned equipment manufacturer GT Advanced. By this method, the silicon is passed through the DSS ingot growth furnace and processed into pure quadratic silicon blocks.
The crystalline silicon PV cell is one of many silicon-based semiconductor devices. The PV cell is essentially a diode with a semiconductor structure (Figure 1), and in the early years of solar cell production, many technologies for crystalline silicon cells were proposed on the basis of silicon semiconductor devices.
