Plexcore® OC in Lighting & Power Applications
Polymer organic light emitting diode (P-OLED) displays and lighting: Used to create a hole-injection layer (HIL) in P-OLEDs (see figure 1), Plexcore® OC ink is a low acid specialty formulation that results in low moisture absorbing films for longer OLED lifetime. The tunable nature of Plexcore® OC ink allows for unsurpassed control of final work function and conductivity of the HIL film—two important parameters that affect the hole injection and charge balance with the light emitting polymer (LEP) films and, ultimately, the overall efficiency of the P-OLED device.
Small-molecule organic light emitting diode (SMOLED) displays and lighting: Plexcore® OC inks can also be used to form HIL films that are compatible with vapor deposited small molecule OLED (SMOLED) devices. The improved hole injection and planarization properties of HIL films printed with Plexcore® OC inks have been shown to extend SMOLED device lifetimes and provide a pathway to future solution-processed SMOLED devices.
Printed solar cells: Plexcore® OC ink is a component of the Plexcore® PV ink system which is designed to maximize the efficiency and lifetime of organic photovoltaic (OPV) solar cells. Used as a hole transport layer (HTL), Plexcore® OC inks work well with a broad range of photoactive layer inks by matching the energy levels of the p/n film (i.e., band gap) by virtue of its tunable work function. HTL films printed using Plexcore® OC inks produce better interfaces with many p/n films than do conventional HTL films. The results are better charge transfer and higher fill factor, which lead to improved device efficiency.
