This research aims to change the coating method to fabricate organic thin film solar cells from the conventional spin system to spray system. In the spray coating method, sprayed solution consists of poly (3-hexylthiophene) (P3HT): [6,6]-phenyl C61 butyric acid methyl ester (PCBM) for solute, and mono chlorobenzene (MCB) for solvent. This paper presents the effect of spray conditions on the deposited organic film characteristics experimentally. As a result, the optimum spray conditions from a viewpoint of discharge rate, spray distance and air pressure were proposed. Moreover, the effect of temperature and humidity as deposition environment was discussed. Finally, several advantages of the spray coating method were performed through the experimental examination.
