Description

Packaging

1, 5,10 g in glass bottle

Application

High-mobility material used for white OLEDs to increase hole injection and transport. It is the best solid-state hole transporting material, to date, used to replace the liquid electrolyte for DSSC solar cells, due to an excellent pore-filling property in nanoporous TiO2 film with pore size of around 30-50 nm; attributed to its small molecular size.

Re:Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the Sublimed Materials for OLED devices .

Usage

   Usage of Spiro-OMeTAD from Inorganic caesium lead iodide perovskite solar cells,Giles E. Eperona, Giuseppe M. Paternòbc, Rebecca J. Suttona, Andrea Zampettibc, Amir Abbas Haghighirada,  Franco Caciallibc and Henry J. Snaitha* :

Subsequently substrates were transferred to nitrogen atmosphere and from this point, during fabrication

and testing, devices were never exposed to ambient air. Perovskite precursor was deposited as described

above. The hole-transporting layer was then deposited via spin-coating a solution of 86.9mg/ml of 2,2',7,7'-

tetrakis-(N,N-di-p-methoxyphenylamine)9,9'-spirobifluorene (spiro-OMeTAD) in chlorobenzene, with

additives of 9.7mg/ml Spiro(TFSI)2 prepared in-house following a published procedure,1 and 10μl/ml 4-tertbutylpyridine.

Spin-coating was carried out in a nitrogen-filled glovebox at 2000rpm. Gold electrodes were

then thermally evaporated under a vacuum of ~10-6 Torr, at a rate of ~0.1nm/s, to complete the devices.
