Abstract
In recent years more than 90% of solar cells are made from crystalline silicon, and nearly 40% of them are based on monocrystalline silicon. To meet the long-term cost target for grid parity, the production of silicon for solar cells must be low cost, which means high productivity and low power consumption without sacrificing quality. Nowadays most monocrystalline silicon ingot is grown using the Czochralski (CZ) method, which is nearly the same as the method used in semiconductor industry, but with a much lower cost. Some is produced using the floating-zone (FZ) technique, but this is disappearing from the solar market. High-throughput seeded casting, or the so-called mono-like (ML) silicon, has also emerged gradually in the market; but there are some challenges ahead for mass production. In this chapter we focus on discussion of the crystal growth technology for CZ and ML solar silicon. Some discussion of the multicrystalline solar silicon is given for comparison. ? 2019 Elsevier Ltd. All rights reserved.
