While average visible transmittance<\/p>\n<p class=\"p1\">(AVT) has been used to address BIPV applications, nothing similar has been defined for agrivoltaics. We introduce<\/p>\n<p class=\"p1\">Average Chlorophyll Transmittance (ACT) to target agrivoltaics applications whose absorbance anticorrelates with<\/p>\n<p class=\"p1\">photopic response used in AVT. We tune an OPV system with a complementary absorption profile to maximize ACT<\/p>\n<p class=\"p1\">via blend ratio variation of the PTQ10 electron donor and DTY6 acceptor molecules processed in non-halogenated<\/p>\n<p class=\"p1\">o-xylene in air. We find that PTQ10 uniquely fits well between chlorophyl absorbance bands, resulting in an ACT<\/p>\n<p class=\"p1\">that is 2x higher than its AVT, and the highest of any system studied. While lowering the concentration of DTY6<\/p>\n<p class=\"p1\">molecules further increases ACT, the performance is reduced significantly due to ineffective acceptor domains as<\/p>\n<p class=\"p1\">analyzed through device dynamics and nanostructure measurements. The best blend results in a Light Utilization<\/p>\n<p class=\"p1\">Efficiency, LUE<span class=\"s1\">C<\/span>= 6.1%, assuming no electrode absorbance.
