We visualized various strategies that have been employed in molecular architecture to improve the stability as well as solubility, and the energy levels are tuned for efficient hole/electron injection, thus leading to high-performance solution processable OTFTs. The obtained mobility was correlated with the molecular stacking pattern and film morphology/microstructure of the semiconductors. Overall, this review presents information that aids reliable OTFT data analysis and provide guidelines for the development of next-generation organic semiconductors. At present, the p-type and n-type OTFTs developed by our group are able to reach the mobilities of over 4.01 and 2.5 cm2V−1 s−1, respectively. In addition, we also demonstrated the utilization of these conjugated moieties in development of high performance dye-sensitized solar cells (DSSCs) and hole transporting materials (HTM) as well as non-fullerene acceptor (NFA) for perovskite solar cells (PSCs). |
