Despite the lowered market share, the equivalent mono-Si PV capacity produced in 2016 was 20.2 GW, indicating a significant increase in the overall production of photovoltaic technologies.[8]. That efficiency leads to better electricity production in the same amount of space and in lower levels of light. 2. Due to the thermal stress of the seed crystal contacting the silicon melt field, the seed crystal is dislocated and these dislocations must be removed by necking growth. Overall, the production process for monocrystalline silicon is mature, and the process for polycrystalline in still maturing. Polycrystalline silicon is a multicrystalline form of silicon with high purity and used to make solar photovoltaic cells. Mono-Si can be prepared as an intrinsic semiconductor that consists only of exceedingly pure silicon, or it can be doped by the addition of other elements such as boron or phosphorus to make p-type or n-type silicon. This process is called tail growth. Creating space-efficient solar panels requires cutting the circular wafers (a product of the cylindrical ingots formed through the Czochralski process) into octagonal cells that can be packed closely together. This energy-intensive step is called chemical vapor deposition (CVD). SunPower monocrystalline panels and LG monocrystalline panels are two of the popular models in this category. Monocrystalline silicon is a good semiconducting material. However, advances in technology are expected to reduce wafer thicknesses to 140 μm by 2026.
