A Study of Charge Transport: Correlated Energetic Disorder in Organic Semiconductors, and the Fragment Hamiltonian

摘要: This dissertation details work done on two different descriptions of charge transport. The first topic is energetic disorder in organic semiconductors, and its effect motivated primarily by solar cells, which can be broadly classified as either inorganic or organic. class cells older, more well-developed, with the most common type being constructed from crystalline silicon. large silicon crystals required for these are expensive to manufacture, gave rise interest photovoltaic made much less costly polymers. These materials also efficient than their counterparts, due a degree spatial disorder. In this document, sources structure semiconductors explored, an emphasis correlations order device function, there must photogeneration exciton (a bound electron-hole pair), transport, dissociation, transport individual charges respective terminals. case thesis, main focus dissociation. effects correlation
