Pyranylidene/thienothiophene-based organic sensitizers for dye-sensitized solar cells

Novel push-pull systems featuring a 4H-pyranylidene donor fragment and thienothiophene as (part of) π-conjugated spacer have been synthesized in order to test their photovoltaic properties. An analogous derivative with two thiophene rings is also included in the study for comparison purposes. The op...
