제목 Effect of Spray Method in Polymer Solar Cell for Active-Polymer Morphology
초록  In a viewpoint of fabrication methods in a Polymer solar cell, the polymer material has limitation because of the wet process. Many research groups have almost used spin-coating method because of performance of solar cell depends on thickness of the active-polymer layer and on the morphology of the electrode-polymer interface. To prove the performance of polymer solar cell by using spray method we tested the sample which was optimizing morphology by varying spray temperature, spray time, and spray pressure. The spray temperature and spray times were involved in pin-hole problem and surface morphology, respectively. The polymer solar cells were fabricated by spray method based on poly(3-hexylthiophene-2,5-diyl)(P3HT) and [6,6]-phenyl-C61 butyric-acid methyl-ester(PCBM) bulk hetero-junctions on PEDOT:PSS layer. In particular, the performance of solar cell using spray method was compared with performance of solar cell using spin-coating method. The maximum PCE of device using spray method was observed 5.012%. The performance of this device was obtained 15.44mA/cm2 of short-circuit current (Jsc), 0.635 V of open circuit voltage (Voc), and 51.1% of fill factor (FF). The PCE of device using spin-coating method was obtained 5.021%. The device that used spray method showed performance similar to spin-coating method. In conclusion, The characteristic differences of polymer solar cell used spin-coating method was only improved by 2.61% of Jsc, 1.82% of FF, and 0.18% of PCE, respectively, compared with the device used spray method.
