Instead of valence and conduction bands, organic molecules feature discrete molecular orbitals:

Analogous to the valence band in inorganic semiconductors.

Instead of Valence and Conduction bands, we speak of HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital). The energy gap between these two determines the material's optical and electrical properties. physics of organic semiconductors pdf

(sigma) bonds with neighboring atoms in a planar configuration. These

). These materials are frequently processed via vacuum thermal evaporation and can form highly ordered, polycrystalline, or single-crystal films. Instead of valence and conduction bands, organic molecules

Graduate students in Materials Science, Physics, and Chemistry. Prerequisites: Basic Quantum Mechanics, Solid State Physics, and Organic Chemistry.

A photon creates a Frenkel exciton in the donor material. (sigma) bonds with neighboring atoms in a planar

that covers modern developments in Organic Photovoltaics (OPV) and OLEDs.

: Rather than moving as free electrons, charges in organic materials typically move as

Because organic films are often amorphous or polycrystalline, charges don't flow smoothly. Instead, they "hop" from one localized molecular site to another. This process is thermally activated; as temperature rises, conductivity typically increases—the opposite of most metals.
