Monocrystalline solar cells are produced from pseudo-square silicon wafer substrates cut from column ingots grown by the Czochralski (CZ) process (see Figure 2). Polycrystalline cells, on the other hand, are made from square silicon substrates cut from polycrystalline ingots grown in quartz crucibles.
The most relevant methods for the production of crystalline silicon for PV applications are the Czochralski method for monocrystalline silicon and directional solidification method for multicrystalline silicon. We study the fabrication of these two types of crystalline silicon in the next sections.
