Guanidine Isothiocyanate Is Not Only Used For Nucleic Acid Extraction, But Also For The Preparation Of Solar Cells

Guanidine isothiocyanate plays an important role in the diagnosis of COVID-19. It is an important component of the diagnostic "gold standard" nucleic acid detection kits. Guanidine isothiocyanate is an uncoupling agent that can inhibit RNase, prevent RNA degradation, and separate nucleic acids from proteins. It is commonly used in denatured lysed cells and nucleic acid extraction. It is widely used in biochemical research and medicine. In addition, guanidine isothiocyanate also plays a role that cannot be ignored in the field of new energy.

According to published reports, in the field of new energy, guanidine isothiocyanate is mainly used as an electrolyte component for the preparation of new types of solar cells such as dye-sensitized solar cells and perovskite solar cells, which have important value for improving the stability of the battery.

Ping Cheng ^[1] et al. Designed a quasi-solid electrolyte with ionic liquid, inorganic layered material, guanidine isothiocyanate, etc. as the main components. It has the characteristics of even distribution of components and good stability, which can be significantly improved Long-term stability and photoelectric conversion efficiency of dye-sensitized solar cells.

Juan Xiong et al. ^[2] prepared a highly efficient perovskite solar cell by doping guanidine isothiocyanate. They introduced guanidine salt and thiocyanate ions to effectively improve the photoelectric efficiency of the perovskite cell.

The experiment proves that the battery efficiency of the battery without the addition of guanidine isothiocyanate drops to about 50% of the initial value under the premise of the same placement for 624 hours, while the battery with guanidine isothiocyanate can still maintain 80% of the initial efficiency . The addition of guanidine isothiocyanate greatly improved the stability of the battery. In addition, the addition of guanidine isothiocyanate can significantly improve the hysteresis of the battery.
