Chapter 21 - Moleculars Materials in Optoelectronics and Photovoltaic Devices

Abstract

Conjugated polymers and low molecular weight organic materials that hold semiconducting properties are a very rich set of possible to use materials with not yet fully explored properties, posing the possibility of producing a huge number of combinations of chemical structures with interesting electronic and optical properties. In these materials the backbone atoms are formed by sp2 hybridization, and electron orbital pz create a system of conjugated π electrons decisive for their semiconductor properties and their suitability for organic optoelectronic devices.
