Guanidine Hydroiodide Usage And Synthesis

Applications

It has been demonstrated that guanidinium iodide (GI) based additives show significant enhancement in carrier lifetimes and open-circuit voltages in hybrid organic-inorganic perovskite solar cells, due to the hydrogen bonding capability of the GI molecule.
Speculation is that hydrogen bonding allows for effective passivation of under-coordinated iodine species located at grain boundaries - both at the surface and internally within the bulk.
Superior performance with cell power conversion efficiencies greater than 17% and an open-circuit voltage of 1.1 V were achieved with device structure ITO/TiO2/perovskite/spiro-OMeTAD/Au.
