Voltage-Current Properties of Polyimide use Electrical Power Installation

전력설비용 Polyimide의 전압-전류특성

We investigate the qualities of organic materials by which can manufacture organic thin films for solar cells and make thin films for insulation layers of an insulated cable. We give pressure stimulation into organic thin films and detect the induced displacement current. In processing of a device manufacture, We can see the process is good from the change of a surface pressure for organic thin films and transfer ratio of area per molecule. The structure of manufactured device is Au/organic thin films(polyimide)/Au and I-V characteristic of the device is measured from 0[V] to +5[V]. The maximum value of measured current is increased as the number of accumulated layers are decreased. The resistance for the number of accumulated layers, the energy density for an input voltage show desired results, and the insulation of a thin film is better as the interval between electrodes is larger.
