Effects of Material Morphology on the Performance of Organic Electronics

The fast-growing organic electronics field has received the attention of a lot of researchers because of its wide applicability in the consumer electronics, photovoltaics and biotechnology. Since the charge transport, absorption of electromagnetic radiations and exciton migration in the organic semiconductors is direction dependent, it is mandatory to control the morphology and orientation of the active layer with respect to the applications. So, in this review we have briefly discussed the role of thin film morphology on the organic solar cell and organic field-effect transistor performance. And the efforts have been taken by the researchers to control the morphology of thin films through the active layer engineering and molecular engineering are summarized.
