文章

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

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.

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.
