Articles

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

Intrinsically stretchable active layers for organic field-effect transistors (OFET) are discussed. Polymer structural modification & post-polymerization modifications are 2 methods to achieve this.

Solution-processed organic photovoltaic devices (OPVs) have emerged as a promising clean energy generating technology due to their ease of fabrication, potential to enable low-cost manufacturing via printing or coating techniques, and ability to be incorporated onto light weight, flexible substrates.

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