In solar cells, single crystal silicon is called "mono" silicon (for "monocrystalline") [15], The temperature gradients in the melt or crystal (in the thermal diffusion boundary layer) can be estimated in one dimension from the conservation of heat flux at the interface: K S G s = K L G L + L ρ R Here K is thermal conductivity, L is latent heat of fusion, ρ is crystal density
Solar energy has been widely developed and utilized as a renewable and clean energy source.

During the growth of Czochralski single crystal silicon, the change of solid–liquid interface shape leads to uneven distribution of thermal stress, and the concentration of thermal stress leads to crystal defects in the process of single crystal formation, which reduces the efficiency of solar cells. In order to avoid a large number of crystal defects caused by the
The continuous Czochralski (CCz) method is a low-cost and high-efficiency method for the production of monocrystalline silicon.

If the emitter is on the front (illuminated side) of the wafer, the electrons have a short path to the conducting layer and impurities in the bulk silicon have limited influence. That is the geometry of the traditional standard solar cell.
PV Solar Industry and Trends Approximately 95% of the total market share of solar cells comes from crystalline silicon materials . The reasons for silicon’s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap.
Semiconductor silicon is focused on crystal diameters up to 450 mm (and potentially 675 mm), while maintaining desired bulk microdefect attributes and reducing costs. Solar single crystal silicon is focused on reducing cost while improving bulk properties for photovoltaic conversion efficiency, such as minority carrier lifetime.
Silicon-based solar cells can either be monocrystalline or multicrystalline, depending on the presence of one or multiple grains in the microstructure. This, in turn, affects the solar cells’ properties, particularly their efficiency and performance.
Over 80% of the world solar cell and module production is currently based on sliced single crystal and polycrystalline silicon cells, so the review is focused on the silicon. Only 13.23% of amorphous silicon (a-Si), 0.39% cadmium telluride (CdTe) and 0.18% of copper indium diselenide (CIS) was used in 2001 world cell/module production .
Silicon is also used for about 90% of all photovoltaic cell material (solar cells), and single crystal silicon is roughly half of all silicon used for solar cells. In solar cells, single crystal silicon is called “mono” silicon (for “monocrystalline”) , .
