: The electron-hole pair is tightly bound to the same molecule. Binding Energy : High energies ( ) keep the pair locked together. Exciton Dissociation

) is strongly dependent on temperature and electric field, often modeled by the for non-adiabatic electron transfer or the Disordered System Models (Bässler Framework) : physics of organic semiconductors pdf

While "p-type" (hole-transporting) materials are abundant, stable and high-performing "n-type" (electron-transporting) materials are still a major area of research. : The electron-hole pair is tightly bound to

Organic semiconductors have revolutionized the fields of optoelectronics and flexible electronics. Unlike traditional inorganic semiconductors such as silicon or gallium arsenide, which rely on rigid covalent crystal lattices, organic semiconductors are carbon-based molecules or polymers held together by weak van der Waals forces. This fundamental structural difference gives rise to unique physical properties, including mechanical flexibility, low-cost solution processing, and tunable optoelectronic properties. When an organic semiconductor absorbs a photon, it

When an organic semiconductor absorbs a photon, it does not immediately create a free electron and hole. Instead, it creates a bound state. Exciton Formation
