Our company focus Perovskite solar cell materials,we always manufacture and supply high quality Our company focus Perovskite solar cell materials, 2,2',7,7'-Tetrakis(N,N -di-p -methoxyphenylamino)-9,9'- spirobifluorene( Spiro-MeOTAD, Spiro-OMeTADCAS 207739-72-8)

We have two kind of Sprio-OMeTAD with difference purifying method.
One is Sublimed ( is often named Sublimed grade).
The other is Recrystallized ( is often named Crude grade).
Most clients prefer Sublimed grade to Recrystallized grade.

Please note that our Spiro-MeOTAD is very strong at current international markets.

We often sell it to many countries' scientific research Institute and University.

We are sure that our Spiro-MeOTAD must be able to meet your clients' requirements.

Spiro-OMeoTAD is used as hole and electron transport layer in Perovskite solar cell (PSC) and Dye-Sensitized Solar Cell ( DSSC), Our Spiro-OMeTAD havegood performance in Perovskite solar cell.

The perovskite solar cell structure is same as TiO2/ Perovskite/ Spiro-OMeTAD/Al
