Photoelectric conversion efficiency. The photoelectric conversion efficiency of the first-line monocrystalline silicon photovoltaic modules on the market is about 18%. In 2017, the single-crystal PERC solar cell reached the world's highest conversion efficiency of 23.45%, and the laboratory data can reach 26%
Attenuation rate. After monocrystalline and polysilicon components have been used in the same environment for the same time, the decay rate of monocrystalline silicon components should be based on polysilicon components. It is assumed that after 10-20 years of use, the photoelectric conversion efficiency of monocrystalline silicon components is higher than that of polysilicon components.
Low light photoelectric conversion efficiency. In low light environment, the photoelectric conversion efficiency of monocrystalline silicon components is also higher than that of polycrystalline silicon components.
