| | 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.
| | Description | 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 . | | Uses | Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents 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. | | Uses | The iodide and bromide based alkylated halides find applications as precursors for fabrication of perovskites for photovoltaic applications. |
