General description

Potassium iodide is widely used as an additive to fabricate perovskite solar cells and light-emitting diodes, to enhance their stability and performance. The excess I− from KI fill in the I−vacancies and suppress potential pathways for ion migration. The K+ cations can bond with undercoordinated halides or passivate negatively charged trap states at the grain surface, which enhances the performance of the device. It can also be used as a catalyst in various reactions such as the synthesis of biodiesel and cyclic carbonates with five-membered rings.
