Here we present efficient upscaling of organic solar cell (OSC) to an active area of similar to 50.4 cm(2) from 0.09 cm(2) using spin coating technique from solution processing. The Solar cell consists of ITO/ZnO/Absorber layer (PBUITT-C:PC71BM)/MoO3/Ag layer and ZnO and absorber layer were coated through spin coating. A mechanical patterning machine was introduced in the fabrication process to make monolithic integrated module for any practical application. All the small area device and module were fabricated and tested in similar conditions. The OSC module (area similar to 50A cm(2)) shows an active area efficiency of 5.4% which is slightly lower than the efficiency (7.3%) of small area OSC (0.09 cm(2)). The open circuit voltage of module shows only similar to 4% drop whereas the current density shows a drop of 8% while upscaling to an active area by > 500 times. This reported, monolithic integrated OSC module performance is due to uniform film thickness with low roughness values at center as well as corner positions obtained by spin coating technique. This demonstrates that spin coating process is suitable for upscaling of organic solar cells. (C) 2016 Published by Elsevier B.V.
