Organic solar cells have attracted much interest due to the potential advantage of the lightness, simple solution processing and flexibility. Until recently, the focus of organic solar cells research has been on optimization of material processing to improve the power conversion efficiency. However, area scaling is an important position for alternative to the market dominating solar cells. Spray deposition technology has advantage of less material wastage and possibility of large scale photoactive area coating when compared with spin coating process. The OPV cell by spray coating tech. shows excellent performance up to the active area of 4 cm2 with the PCE of ~3.0 % under AM.1.5 simulated illumination with an intensity of 100mW/cm2. This indicates that the spray deposition process can be used as a mass production process for evaluating large-area organic solar cells. |
