B. Solution-Liquid-Solid Growth of Indium Phosphide Fibers from Organometallic Precursors: Elucidation of Molecular and Nonmolecular Components of the Pathway
Solution-phase organometallic syntheses of semiconductors are used for the growth of high-quality quantum dots,1-3 and are potentially useful for the deposition of semiconductor materials on thermally sensitive substrates such as polymers
Organic solar cell
a photovoltaic cell that uses organic electronics like conductive organic polymers or small organic molecules for light absorption and charge transport
Basic principle of solar cell
When light is illuminated at cell, the photons are absorbed in the organic layers.
The excitons diffuse to interface between donor and acceptor.
The excitons are separated by electron
An organic light emitting diode (OLED) is a solid state device like the LED but composed of several layers in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
Function of each part
Cathode : injecting electron composed of metal
Anode : injecting hole composed of transparent ITO
Emissive polymer : reco
