In this article we demonstrate the use of a blend made of two regioregular polythiophenic derivatives, namely poly(3-methylthio)thiophene and poly(3-hexyl)thiophene, to obtain conductive traces by the simple laser exposure of their thin films to a suitable laser source. The polymeric blend was also tested as a photoactive layer for BHJ solar cells, showing an improved surface morphology and a wider absorp- tion spectrum, thus resulting in an enhanced photovoltaic performance. In the standard condition nor- mally used for the cell preparation, we obtained a 3.16% power conversion efficiency. The device showed good reproducibility and stability over time

The polymeric blend was also tested as a photoactive layer for BHJ solar cells, showing an improved surface morphology and a wider absorp- tion spectrum, thus resulting in an enhanced photovoltaic performance.
