商品

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

Organic materials in optoelectronic devices like LEDs and solar cells are of significant academic and commercial interest.

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.

Thin, lightweight, and flexible electronic devices meet widespread demand for scalable, portable, and robust technology.
