Abstract

8-hydroxy quinoline aluminum is an organic semiconductor material and has broad application prospect in the field of solar cell application. In order to study the transport dynamic information of carriers, 8-hydroxyl quinoline aluminum thin film was prepared under the condition of constant temperature. The method of X-ray diffraction was used to analyze the properties of the film and the method of time-of-flight(TOF) was used to study the experimental conditions affecting the carrier mobility by theoretical analysis and experimental verification. The results show that this method is feasible. The carrier transport law of 8-hydroxy quinoline aluminum in the temperature range of 308K~338K is in accordance with shallow trap model. When the sampling resistance is less than 15kΩ and pulse energy is less than 3.5μJ, the carrier TOF remains constant. The test results are reliable. The result is helpful for the preparation of organic solar cells.
