A simple wiper coating method was introduced to coat large area of PEDOT:PSS film for the polymer solar cell module. A thin and smooth film of PEDOT:PSS was prepared by the method. The efficiency of 4.46% was obtained from the single cell having wiper-coated PEDOT:PSS layer. The efficiency is comparable to the polymer single cell prepared by spin coating method. The atomic force microscopy result confirms that the surface of the film prepared by the coating method is smooth uniform. The large area module was prepared by the method and the VOC of 5.30 V, ISC of 19.88 mA and FF of 53.29% was obtained from the polymer solar cell module. The resulted power conversion efficiency was 1.21% with on aperture size 46.2 cm2.
