In this study, measurement techniques of nonradiative process in organic semiconductor thin film devices were developed by using microphone technique and transducer technique. In microphone technique, measurement cell was made up of silicon rubber and a substrate of devices, and it is demonstrated that the photo-acoustic signal and the photocurrent signal under applying voltage were measured at the same time. As a result of that, the both characteristics show good agreement under applying voltage and red illumination light,On the other hand, in a transducer technique, output signal was increasing with increasing the film thickness.

本研究发展了有机半导体薄膜器件无辐射过程的传声器技术和传感器技术。在传声器技术中，利用硅橡胶和器件衬底构成测量池，实现了在外加电压下同时测量光声信号和光电流信号。其结果是，这两个特性在施加电压和红色照明光下显示出良好的一致性。另一方面，在换能器技术中，输出信号随着膜厚度的增加而增加。
