General description

We are committed to bringing you Greener Alternative Products,which adhere to one or more of The 12 Principles of Greener Chemistry. This product is an enabling product used as a Hole Transport Material for high-performance solar cells and thus has been enhanced for energy efficiency. Click here for more information.

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.

High-efficiency hybrid solar cells are fabricated using a simple approach of spin coating a transparent hole transporting organic small molecule, 2,2',7,7'-Tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene (Spiro-OMeTAD) on silicon nanowires (SiNWs) arrays prepared by electroless chemical etching. The characteristics of the hybrid cells are investigated...

Solar panels for homes and businesses have seen a rise in demand over the past few years as we move toward more environment-friendly and sustainable energy sources. In 2010, the average power from solar was just 5.0 GWh/d and the Energy Information Administration (EIA) expects this to be 90 GWh/d in 2016.
