: Used in smartphone and TV screens. Electricity is converted into light when electrons and holes recombine in the organic layer.

The defining physical characteristic of OSCs is the formation of delocalized $\pi$-electron systems. Because these electrons are loosely bound, they can be excited across energy gaps typically ranging from 1.5 to 3 eV, placing OSCs in the visible light spectrum regime. However, unlike the rigid lattice of silicon, OSCs are Van der Waals solids; the weak intermolecular forces lead to localized electronic states and significant structural disorder. physics of organic semiconductors pdf

hybridization. This creates a chain of alternating single and double bonds. The remaining orbitals overlap to form a delocalized -electron cloud. Because these electrons are loosely bound, they can
