Customer ServiceMulticrystalline CZ or FZ ingots are more highly stressed than cast multicrystalline ingots, and the grain boundaries are more electrically active, resulting in poorer cell efficiency. If ingot growth is initiated single crystalline but not dislocation free, the ingots soon become multicrystalline (an exception is the special case of using a tricrystalline seed [ 51.19 ]).

Multicrystalline cells are cheaper to produce than monocrystalline ones because of the simpler manufacturing process required. They are, however, slightly less efficient, with typical module efficiencies around 13–15% (Price and Margolis, 2010) and high-end products up to 17% (RENI, 2010).
Multicrystalline silicon cells. Multicrystalline cells, also known as polycrystalline cells, are produced using numerous grains of monocrystalline silicon. In the manufacturing process, molten polycrystalline silicon is cast into ingots, which are subsequently cut into very thin wafers and assembled into complete cells.
In the past years, research on n-type multicrystalline silicon revealed its large solar cell efficiency potential.
Multicrystalline cells are produced using numerous grains of monocrystalline silicon. In the manufacturing process, molten multicrystalline silicon is cast into ingots, which are subsequently cut into very thin wafers and assembled into complete cells.
The most prominent difference between mono- and multicrystalline silicon is the presence of structural crystal defects such as grain boundaries in multicrystalline material. Especially in high-performance mc-Si, recombination-active grain boundaries have been identified to account for the majority of material-related losses , .
