| 제목 | SYNTHESIS AND CHARACTERIZATION OF NOVEL STRUCTURES VIA GREEN SELECTIVE OPD WITH ABSORPTION WAVELENGTH SELECTIVITY |
| 초록 | An image sensor is a photoelectric conversion device using semiconductor materials used in cameras, photocopiers, and medical diagnostic devices. Since the color filter itself absorbs the incident light to some extent, the quantum efficiency of the final device is greatly reduced. Recently, organic semiconductors have been reported to replace the role of Si in the field of photodiodes in order to overcome the disadvantages of Si. This is a great advantage compared to Si as a photoactive layer in a photodiode because it does not require a color filter. In this work, we synthesized a donor with novel green selectivity. The general characteristics of the unit are its planar molecular structure, high atmospheric pressure stability and strong electron donating ability, all of which can be related to its excellent electrical properties. It has been found that with appropriate acceptor units and synthesis, it is possible to have a narrow absorption band for the green range. |
