Abstract
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.
