Optoelectronic materials
01
Light Emitting Diodes
Organic Thin Film Transistors
Solar Cells
Flexible Printed Electronics
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.

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

Perovskite Solar Cell
Light-harvesting active layer

• Perovskite/silicon tandem solar cells have
  reached efficiencies above 25 in just about
  three years of development, mostly driven by the
  rapid progress made in the perovskite solar cell
  research field.

11
Photonic and Optical Devices

• Photonic and Optical devices are components for
  creating, manipulating or detecting light or
  electromagnetic radiation.

Laser diodes
Solar and photovoltaic cells
Light-emitting diodes
Displays and optical amplifiers
12
Solution-Processed OLED

• OLEDs have the key advantage that they may be
  manufactured entirely through solutions.

13
Thermally Activated Delayed Fluorescence (TADF)
OLED

• TADF materials can achieve 100 of the exciton
  formation generated by electrical excitation at
  S1.
