General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

Guanidinium bromide finds applications in organic electronics as an additive or dopant inorganic semiconductors or conductive polymers. It can modify the electrical properties, such as conductivity or charge transport of the materials used in electronic devices.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.
