Title Fabrication of Organic Photoelectric Films and Their Optical Measurement
Abstract Organic photovoltaic (OPV) cells are light weight, flexible, and low cost, as well as can be made in large area. The research on OPV has become one of the hottest topics in recent years. Regio-regular poly (3-hexylthiophene) (RR-P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) are model materials. Using P3HT as the electron donor material and PCBM as the electron acceptor material, we can get the different structure of blends solar cell and its efficiency has exceeded 5%. In order to explore the impact factors on solar cell conversion rate during the film production process, the subject plans to explore the light excited state and the photo-generated carrier changes under different annealing conditions in organic photovoltaic materials. We use phase sensitive technology to measure photoinduced absorption spectroscopy as well photoluminescence spectroscopy of organic thin films at various temperatures. This work chooses two kinds of organic photoelectric materials named P3HT and PCBM, and measures the absorption spectra and photoluminescence spectra of the thin films made of 20 mg/ml of pure P3HT and P3HT: PCBM (1:1) mixed solution under condition of unannealed treatment and annealed treatment in a range of temperatures. In this subject research, we can obtain the following conclusions: the choice of annealing
