Description

technical field

[0001] The invention relates to the field of optoelectronic technology, in particular to a photovoltaic type organic semiconductor detector. Background technique

[0002] Organic Infrared / Ultraviolet Semiconductor (Organic Infrared / Ultraviolet Semiconductor) is defined as the following class of materials: organic small molecules, organometallic complexes, organic oligomers or polymers that have photoelectric or photovoltaic effects in the infrared / ultraviolet band of electromagnetic waves . Such materials are different from infrared / ultraviolet inorganic semiconductors in that the intermolecular forces are dominated by van der Waals forces, hydrogen bonds, π-π electron forces, and coordination bonds, so they are different from molecular Inorganic infrared / ultraviolet semiconductor materials mainly rely on covalent bonds, ionic bonds and other forces, and organic infrared / ultraviolet semiconductor materials can prepare thin films on single crystal, polycrysta...
