OFETandSensingApplications
Theexceptionalhighmobilityofthispolymerofupto10cm2/Vs[2]viasolution-processedtechniques,combinedwithitsintrinsicairstABIlity(evenduringannealing)hasmadePDPP2T-TT-OD ofsignificantinterestforOFETandsensingpurposes.

Inourowntests,wehavefoundthatbyusingsimplespin-coatingontoanOTS-treatedsiliconsubstrate(usingourprefabricatedtestchips),highmobilitiescomparableto theliteraturecanbeachieved (1-3cm2/Vs).FurtherimprovementsmayalsobepossIBLewithmoreadvancedstrain-inducingdepositiontechniques.
PhotovoltaicApplications
