Simple transfer from spin coating to blade coating through processing aggregated solutions

We observe that thin film solar cells based on poly[5-(2-hexyldecyl)-1,3-thieno[3,4-c]pyrrole-4,6-dione-alt-5,5-(2,5-bis(3-dodecylthiophen-2-yl)-thiophene)] [P(T3-TPD)] blended with phenyl-C₇₁-butyric acid methyl ester (PC₇₁BM) are remarkably robust to process variations, optimizing under identical conditions for both spin and blade coating.
