The doping process is an integral part of the production of monocrystalline silicon solar cells. It is used to introduce impurities energy into the pristine silicon wafers and to create the p-type and n-type semiconductor layers. Each of these is necessary for ensuring operational features of the p-n junction, which is used to convert sunlight into electrical energy.
In the field of solar energy, monocrystalline silicon is also used to make photovoltaic cells due to its ability to absorb radiation. Monocrystalline silicon consists of silicon in which the crystal lattice of the entire solid is continuous. This crystalline structure does not break at its edges and is free of any grain boundaries.
The crystallization process of polycrystalline silicon with a random crystallographic orientation of grains is faster and cheaper; however, the solar cells produced from them offer lower efficiency than the cells produced of its monocrystalline form due to structural defects present .
Monocrystalline silicon is typically created by one of several methods that involve melting high-purity semiconductor-grade silicon and using a seed to initiate the formation of a continuous single crystal. This process is typically performed in an inert atmosphere, such as argon, and in an inert crucible, such as quartz.
Monocrystalline silicon cells can absorb most photons within 20 μm of the incident surface. However, limitations in the ingot sawing process mean that the commercial wafer thickness is generally around 200 μm. This type of silicon has a recorded single cell laboratory efficiency of 26.7%.
Silicon is a vital part of integrated circuits and solar panels. In the photovoltaic system, solar panels made of monocrystalline wafers give higher efficiency than polycrystalline. A finished monocrystalline silicon ingot at the National Museum of Scotland [Credit: Wikipedia /cc]
The monocrystalline silicon workpiece is crystallized in the diamond lattice as shown in Figure 27, which is a special cubic crystal structure. In the face-centered cubic crystal, atoms are located at the corners and at the face centers. Based on the face-centered cubic crystal, the diamond lattice has four further atoms located inside the lattice.
