Dye sensitized solar cells (DSSCs) tau nyiam ntau yam nyob rau xyoo tas los no vim yog kev tsim cov nqi qis dua piv rau silicon-based thiab nyias zaj duab xis hnub ci.Txawm li cas los xij, platinum yog cov khoom siv catalytic zoo heev los siv rau hauv kev npaj cov txee electrodes (CEs) rau DSSCs nws kim heev.Lwm txoj hauv kev los hloov cov platinum (Pt) uas tau kuaj xyuas yog cov ntaub ntawv carbon, conductive polymers thiab hybrids.Hauv kev ua haujlwm no, txee electrode rau DSSCs tau tsim siv cov khoom siv carbon tau los ntawm graphitization ntawm sucrose ntawm qhov kub thiab txias.Lub slurry ntawm cov pa roj carbon monoxide tsim los ntawm sucrose graphitization tau tsim nrog polyvinylpyrrolidone (PVP) raws li surfactant thiab txheej tau los ntawm kws kho mob blading slurry hla FTO iav substrate.Qhov ceev tam sim no (Jsc) thiab qhib hluav taws xob hluav taws xob (V (OC)) ntawm cov xov tooj ntawm tes (chaw 0.25 cm (2)) yog 10.28 mAc m (-2) thiab 0.76 V raws li.Qhov ua tau zoo ntawm cov xov tooj ntawm tes yog 4.33% uas tsuas yog qis dua qhov tau txais rau cov hlwb zoo sib xws siv platinum raws li counter electrode.
