Why Use Low Work Function Electron Transport Solutions?

Low work function electron transport solutions are a key way of assisting the movement of electrons using the lowest amount of energy required.

Using Low Work Function Electron Transport Solutions in OLED TV Screens

A common reason for using low work function electron transport solutions is in the dispersal of energy required in OLED TV screens.  Solution processing of organic light emitting diodes (OLEDs) is cost-efficient and becoming increasingly accessible and is fast replacing traditional manufacturing methods to enhance the position of OLED technology in the display market.  

At Avantama, we have around 30 distinct formulations which can be used for both hole and low work function electron transport applications respectively. We can offer a suitable solution for most modern printing techniques, supporting the production of many OLED devices using doctor blading, roll-to-roll coating and ink jet printing. We are also able to provide custom design and synthesis services which can assist in the development of proprietary formulations for unique  electrochemical requirements.

Avantama N-11 is a low work function electron transport solution which is made up of 12 nanometer (nm) zinc oxide (ZnO) nanoparticles in a blend of alcohols. It can be used with silver nanowires and Perovskite absorbers and is extremely well-suited for a broad variety of end-product architectures and functions. This low work function electron transport solution can be deposited via a range of tried-and-tested methods including  spin coating, hole blocking, doctor blading, and slot die processing.

Low Work Function Electron Transport Solutions for Multilayer Photovoltaic Systems

At Avantama, we have produced a range of nanoparticle formulations which can be used for multilayer photovoltaic systems. Our low work function electron transport solutions are able to carry out both electron injection and hole blocking functions meaning that photon conversion can take place with excellent quantum efficiencies. These can then be used for a range of application techniques such as high throughput roll-to-roll processing.

Standard vacuum-based evaporation production of Perovskite solar cells and organic photovoltaic (OPV) platforms is both time-consuming and expensive. Removing the bottleneck in photovoltaics manufacture is a critical stage in meeting increasing demand and manufacturing new solar cell techniques with improved power conversion efficiencies. More rapid production capacities and enhanced multilayer performance, solution-processed solar cells are crucial for the future development of photovoltaics.
