crisis present in the world. solution processing of such devices allows large scale production using roll-to-roll process and similar fabrication processes. Lasers can be used for selective ablation of different layer of such solar cells for structuring. This work aimed at fabricating flexible polymer solar cells with all layer processed from solution as well as investigating the effect of laser for structuring different layer of the solar cells fabricated. To fabricate the solar cells, well-established photoactive blends from poly-(3-hexylthiophene-2,5-diyl) and [6,6]-phenyl C61-butyric acid methyl ester (P3HT:PC61BM) was used. The solar cells were comprised of solution processed silver as cathode and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS) as anode while zinc oxide (ZnO) was used as electron transport layer. An infrared laser was used to structure different layers of the solar cells and assess the effect on the layers. For fabrication, different layers were processed by lab-scale solution-based techniques such as doctor-blading, horizontal dipping and spin coating. Processing parameters for fabricating each layer were optimized experimentally and the solar cell fabricated with optimal parameters showed reasonable power conversion efficiency. Also, the analysis of structuring different layer of solar cells using an infrared laser is presented.
