[Abstract]:Organic solar cells have attracted much attention because of their simple fabrication process, low cost, flexibility and so on. With the continuous improvement of photoelectric conversion efficiency of organic solar cells, the need for large-scale production of organic solar cells is becoming more and more prominent. In recent years, many new technologies for mass production of organic solar cells compatible with roll-to-roll technology have been developed, in which spraying technology has been widely used because of its simple equipment, high material utilization and low demand for substrates. Although some progress has been made in the preparation of small-size organic solar cells by spraying technology, its application in the preparation of large-area organic solar cells is still rare and lack of systematic research and analysis. Based on the mature material and structure of organic battery, this paper improves the performance of small area devices by optimizing the spraying conditions of anode buffer layer and organic functional layer, on the basis of which, large size organic solar cell devices are fabricated by spraying technology, and the performance of small area devices is improved by optimizing the spraying conditions of anode buffer layer and organic functional layer. And explore which structure and spraying process of large-size organic solar cell device performance is the best. The main contents are as follows: first, the spray flow rate and solution concentration of poly (3,4-ethylenedioxythiophene: polystyrene sulfonate) (PEDOT:PSS) film prepared by spraying technology were explored. The original PEDOT:PSS solution was diluted by deionized water. The influence of volume fraction of original PEDOT:PSS solution and substrate temperature on the performance of organic solar cell devices. The experimental results show that when the spray flow rate is 100 ulmin, the solution concentration is 66.7% and the substrate temperature is 100 鈩，
