Monocrystalline silicon wafer is one major type of silicon wafer that can convert sunlight into electricity. The other one is polycryatalline silicon wafer. When compared to polycryatalline silicon wafer, monocrystalline silicon wafer not only requires high purity raw materials,but also have relatively complicated production process. Thus, cost of monocrystalline silicon wafer is much higher than polycrystalline silicon wafer. The converting ratio of single crystal silicon could be up to 19%, which is much higher than polycrystalline silicon, and single crystal silicon is the main material that used to produce monocrystalline silicon wafer.
