A study reviews the applications of organic semiconductors in two of the most active fields of organic optoelectronics: organic thin-film transistors (OTFTs) and organic solar cells (OSCs). Polymer semiconductors having a common structural component, the imide or amide functional group, connected to π-conjugated cores are specifically discussed in the study. Three critical OTFT performance parameters are charge carrier mobility, current modulation ratio, and threshold voltage. The performance parameters can be derived from the OTFT output and transfer characteristics.
