This paper reports the pilot scale roll-to-roll (R2R) printing of flexible organic solar cell modules with conventional structure. In this module configuration, eight cells are monolithically series connected in order to increase the module output voltage to a desirable level for applications. Indium tin oxide (ITO) used as a hole contact is patterned with screen printing to a rectangular shaped cells with a spacing of 1 mm. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) which acts as an hole injection layer and photoactive layer based on poly-3-hexylthiophene (P3HT) and [6.6]-phenyl-C61-butyric acid methyl ester (PCBM) blend are pre-pared using R2R gravure printing. The sheet evaporated electron contact material of lithium fluoride/aluminium (LiF/Al) is applied for R2R printed modules.
