Low Work Function Modifiers: PEI's Role in Organic Electronics
The field of organic electronics, encompassing technologies like organic solar cells (OSCs), organic light-emitting diodes (OLEDs), and organic field-effect transistors (OFETs), is constantly seeking materials that can optimize device efficiency and performance. Polyethyleneimine (PEI), particularly its modified forms like PEI ethoxylated (PEIE), has gained significant attention as an effective low-work function modifier for electrodes in these devices.
The work function of an electrode is a critical parameter that influences charge injection and extraction in organic electronic devices. By applying a thin layer of PEI or PEIE to electrode surfaces, the work function can be universally reduced. This modification facilitates better energy level alignment between the electrode and the active organic layers, leading to improved charge injection efficiency. For OSCs, this translates to higher power conversion efficiencies, while for OLEDs, it can result in lower operating voltages and enhanced brightness.
The appeal of PEI as a modifier lies in its solution-processability, allowing for cost-effective manufacturing through methods like spin-coating or printing. This feature is crucial for the scalability of organic electronic devices. Furthermore, PEI's ability to modify a wide range of materials, including metals, metal oxides, and conductive polymers, makes it a versatile tool for device engineers.
