Solution processing of polymer photovoltaic solar cells in air or under inert atmosphere
Résumé
Polymer photovoltaic solar cells based on a blend of poly(3-hexylthiophene) (P3HT) blended with [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) have been manufactured in air under ambient conditions and under inert atmosphere in a nitrogen-filled glovebox (O2 and H2O < 0.1 ppm). The solution processing of the active layer, in air or nitrogen, affects the performances of the resulting devices. However, the air processed devices shows reasonable efficiencies implying that somehow large area processing of such materials using machinery in air under ambient conditions is realistic for the high throughput production of polymeric solar modules.
