Perovskite precursor inks to kick-start your perovskite photovoltaic research
Perovskite Precursor Ink (for Air Processing)
A formulation of methylammounium iodide (MAI) and lead chloride in a DMF solvent that upon processing in air can be used to create a CH3NH3PbI3-xClx perovskite film.
Perovskite Precursor Ink (for Nitrogen Processing)
A formulation of methylammounium iodide (MAI), PbCl2 and PbI2 at a molar ratio of 1:1:4 (PbCl2:PbI2:MAI) in a DMF solvent. On processing, I201 ink can be used to create a CH3NH3PbI3-xClx perovskite film. The process recipe for I201 is optimised for glovebox processing under a nitrogen atmosphere.
Perovskite Precursor Materials
Precursor materials for forming perovskite thin films for photovoltaic and OLED purposes.
Formamidinium Bromide (FABr)
Formamidinium bromide (FABr), is used mainly as a perovskite precusor material for FAPbBr3 or a range of formamidinium lead bromide-iodide mixed halide perovskites (FAPbIyBr3-y). FAPbBr3 material, having an energy bandgap of 2.23 eV, makes it an ideal candidate for tandem solar cell applications as well.
Formamidinium Iodide (FAI)
Formamidinium lead iodide shows a narrower bandgap than the commonly used methylammonium lead iodide (1.48 eV compared to ~1.57 eV), and hence lies closer to that favourable for optimum solar conversion efficiencies. With an approach of FAPbI3 crystallisation by the direct intramolecular exchange of dimethylsulfoxide (DMSO) molecules intercalated in PbI2 with formamidinium iodide, device with performance over 20% has been fabricated.
High purity (99.999%) lead chloride suitable for fabricating perovskite solar cells.
MAI (Methylammonium Iodide)
Methylammonium iodide (MAI) is a precursor for the synthesis of organic-inorganic hybrid perovskites for use in FETs, LEDs and PVs. Due to the high purity of the methylammonium iodide (99.99%) it should be noted that there is a reduced solubility within dimethyl formamide and dimethyl sulfoxide. The reduced solubility is due to the removal of trace amounts of residual hydroiodic...
Methylammonium bromide (MABr)
Methylammonium bromide (MABr) is the precursor of MAPbBr3 perovskites. Having a bandgap of 2.3 eV (HOMO 5.68 eV, LUMO 3.38 eV) , MAPbBr3 perovskites has been used to tune the bandgap of mixed MAPbX3 (where X is the halide I, Br and/or Cl mixtures).
