Optoelectronic Materials

Optoelectronic materials have been known for nearly a century. In the late years, the interest in this material is attribute to the discovery of electroluminescence in molecular crystals and conducting polymers. Due to the significant improvements in material design and purification, the field of optoelectronic materials has caused great interest. At present, organic materials have received considerable attention due to their application in electronic and optoelectronic devices such as organic thin film transistors, light emitting diodes (OLEDs), solar cells, flexible printed electronics and so on.

Optoelectronic Materials

Optoelectronic materials at Alfa Chemistry include:

Dye-Sensitized Solar Cell (DSSC): Dye-sensitized solar cell (DSSCs) is low-cost solar cell belonging to the category of thin-film solar cells. It is based on a semiconductor formed between an electrolyte and a photo-sensitized anode. DSSC has many attractive features: it is easy to make use of conventional roll-printing techniques, and most of the materials used are low-cost.

Optoelectronic Materials

Electrode: An electrode is an electrical conductor for making contact with a non-metallic portion of a circuit. Electrodes are used to provide current through non-metallic object and to measure the electrical conductivity for many applications, such as fuel cells, EEG (for recording brain activity), electrophysiology techniques in biomedical research and so on.

Flexible Printed Electronics: Flexible print electronics combines the microelectronics, electronics assembly and printing industries. This technology makes it possible to print circuits, sensors, memories, batteries and displays onto thin, lightweight, flexible substrates.

Organic Light Emitting Diode (OLED): An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. The layers are situated between two electrodes. OLEDs are used in manufacturing digital displays in devices such as television screens, computer monitors, mobile phones and PDAs.

Optoelectronic Materials

Organic Photovoltaic (OPV): Organic photovoltaic (OPV) solar cells are designed to provide earth-rich and low-energy photovoltaic (PV) solutions. This technology has the theoretical potential to provide electricity at low cost.

Organic Thin-Film Transistor (OTFT): Organic thin film transistor (OTFT) technology involves the use of organic semiconductor compounds, particularly computer displays. These displays have high brightness, vivid colors, and are easy to read in most ambient lighting environments.

Perovskite Solar Cells: A perovskite solar cell is the solar cell that includes a perovskite structure compound, in which a hybrid organic-inorganic lead or tin halide-based material is used as a light-harvesting active layer. Perovskite materials such as methylammonium halides are inexpensive to produce.
