Besides nucleic acid extraction, guanidine thiocyanate is also used in the preparation of solar cells

Guanidine thiocyanate plays an important role in the diagnosis of pneumonia caused by New Coronavirus. It is an important component of the "gold standard" nucleic acid detection kit. Guanidine thiocyanate is a kind of uncoupling agent, which can inhibit RNase, prevent RNA degradation, and separate nucleic acid from protein. It is often used for denaturation and lysis of cells and nucleic acid extraction. It is widely used in biochemical research and medicine. In addition, guanidine thiocyanate also plays an important role in the field of new energy.

According to published reports, in the field of new energy, guanidine thiocyanate is mainly used as an electrolyte component to prepare new solar cells such as dye-sensitized solar cells and perovskite solar cells, which is of great value to improve the stability of cells.

Cheng Ping et al. Designed a quasi-solid electrolyte with ionic liquid, inorganic layered materials and guanidine thiocyanate as the main components, which has the characteristics of uniform component distribution and good stability, and can significantly improve the long-term stability and photoelectric conversion efficiency of dye-sensitized solar cells.

Xiong Juan et al. Prepared an efficient perovskite solar cell by doping guanidine thiocyanate. They effectively improved the photoelectric efficiency of perovskite solar cell by introducing guanidine salt and thiocyanate ion. Experiments show that the battery efficiency without guanidine thiocyanate decreases to about 50% of the initial value, while the battery with guanidine thiocyanate can still maintain 80% of the initial efficiency. The addition of guanidine thiocyanate greatly improved the stability of the battery. In addition, the addition of guanidine thiocyanate can significantly improve the hysteresis of the battery.
