High-Performance Semiconductor Polymers Based on Diketopyrrolopyrrole and Thienothiophene

The development of high-performance conjugated organic molecules and polymers has received widespread attention in industrial and academic research.

Optoelectronic Devices Based on Diketopyrrolopyrrole (DPP)-containing Conjugated Small Molecules

Optoelectronic devices such as light-emitting diodes (LEDs), solar cells, and light-emitting field effect transistors (FETs) that utilize organic materials as their light harvesting and/or charge transporting component have been the subject of much academic and commercial attention.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Flexible Organic Transistors for Biomedical Applications

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.
