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

Perovskite Metal Complexes in Photovoltaics

Solar panel demand surges for sustainable energy, with power output rising from 5.0 to 90 GWh/d from 2010 to 2016.

Towards Greener Organic Transistor Sensors

Explore the eco-friendly potential of organic thin film transistors (OTFTs) for detecting chemical analytes, identifying viruses, and assisting in health diagnostics. This mini-review highlights challenges of achieving sustainability, safety, and biodegradability of each component of an OTFT sensor.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm

Ultra-High Efficiency Perovskite-Perovskite Tandem Solar Cells

Next generation solar cells have the potential to achieve conversion efficiencies beyond the Shockley-Queisser (S-Q) limit while also significantly lowering production costs.
