| Summary: | 碩士 === 國立聯合大學 === 材料科學工程學系碩士班 === 101 === In this study, we focused on the inorganic/organic hybrid solar cells. We used ZnO nanorods by grown hydrothermal method, and then spin coated P3HT:PCBM on ZnO nanorods. Finally, evaporated Ag. The device of this structure as standard device. We use 3-hydroxyflavone to modified as a interlayer of the inorganic/organic interface, and hope increased device’s performance and life.
We tried four different structures compared with standard device, and found added 3-hydroxyflavone could effectively improve the PCE. We were also did the life time test, and found added 3-hydroxyflavone can extended the life of devices.
According to the result of this thesis, the main reasons for the increased PCE of solar cells can be attributed to enhanced FF. Because of series resistance decreased and shunt resistance increased. As a result charges can transfer from active layer to ZnO nanorods more unhindered. In accordance with the conclusions of this thesis, we can create a more excellent organic solar cells in the future.
