Denne protokol giver et middel til at opnå foton opkonvertering forbedret DSC og detaljer om, hvordan man korrekt måle en sådan anordning. FOM giver mulighed for simpel beregning af de forventede ΔJ SC forbedringer kan forventes ved forskellige lysintensiteter, herunder på 1 solen. De her viste værdier er invariant med lysintensitet (indsat i figur 4), som pr forventning, når systemet er under mætning tærskel 33. Med FoM kan vi standardisere ekstraudstyr effekt af TTA-UC e...

Dye-sensibiliserede solceller (DSC) er blevet udråbt som et lovende koncept i overkommelig solenergi kollektion 1-3. På trods af denne entusiasme, har udbredt kommercialisering endnu at forekomme. En række årsager er blevet fremført for dette, med et presserende problem er den forholdsvis høje energi absorption debut, begrænser den opnåelige lyshøstende effektiviteten af disse enheder 4. Selv om dette kan overvindes, sænke absorption debut typisk ledsaget af et fald i tomgangsspænding, som i uforholdsmæssig grad udhuler eventuelle gevinster i strømtæthed 5, 6. Den generelle drift af DSC involverer elektron overførsel fra en photoexcited farvestof til en halvleder (typisk TiO2), efterfulgt af regenerering af det oxiderede farvestof ved en redox mægler. Begge disse processer synes at kræve betydelige drivkræfter (potentielle) for at fortsætte med høj effektivitet 7 </sup&gt;. Med sådanne betydelige iboende tab, bliver det klart, at den optimale absorption debut for disse enheder er rimelig højt energiindhold. Tilsvarende problemer eksisterer for økologiske solceller (OPV), hvilket skyldes igen at de store kemiske drivkræfter, der er nødvendige for en effektiv opladning separation. Følgelig forudsigelser af øvre sol-til-elektrisk omdannelseseffektivitet grænser for enkelt junction enheder baseret på begge disse teknologier indebærer absorbenter med brede (effektiv) båndgab 4. For at overvinde den lyshøstende rejste spørgsmål ovenfor er der blevet taget en række tiltag. Dette omfatter &quot;tredje generation&quot; 8 tilgange tandem strukturer 9, 10 og foton opkonvertering 11-14. For nylig 11 vi rapporteret en integreret enhed, der består af en DSC-arbejds-og modelektroden, med en triplet-triplet udslettelse baseret op-konvertering (TTA-UC) system indbygget itil strukturen. Dette TTA-UC element var i stand til at høste rødt lys transmitteres gennem det aktive lag og kemisk konvertere det (som beskrevet detaljeret nedenfor) til højere energi fotoner, der kan absorberes af det aktive lag af DSC og generere fotostrøm. Der er to vigtige punkter at bemærke om dette system. For det første TTA-UC har mange potentielle fordele frem for andre foton opkonvertering systemer 11; For det andet viser en mulig arkitektur (proof-of-principle) til inkorporering af TTA-UC, som havde manglet fra TTA-UC litteratur op til dette punkt. Processen TTA-UC 15-24 involverer excitering af &#39;overfølsomhed&#39; molekyler, i dette tilfælde Pd porphyriner med lys med energi under enheden indtræden energi. Singlet-begejstrede sensibilisatorer undergå hurtig intersystemkrydsning til det laveste energi triplet tilstand. Derfra kan de overføre energi til en grundtilstand triplet-accept &quot;emitter &amp; #8217 arter såsom rubrene, så længe overførslen er tilladt ved fri energi 25. Den første triplet tilstand rubrene (T 1) er større end halvdelen af den energi af sin første exciterede singlet-tilstand (S 1), men mindre end halvdelen af den energi T 2, hvilket betyder, at et møde kompleks af to triplet-exciterede rubrenes kan tilintetgøre til give én singlet ophidset emitter molekyle (og den anden i grundtilstand) med en temmelig høj sandsynlighed. Andre stater, statistisk forudsagt er mest sandsynligt energisk utilgængeligt for rubrene 26. Singlet ophidset rubrene molekyle kan derefter udsende en foton (som pr fluorescens) med energi nok til at excitere farvestoffet på arbejdsmiljøet elektrode af DSC. Denne proces er vist i Animation 1. TTA-UC giver en række fordele i forhold til andre UC-systemer, såsom en bred absorption rækkevidde og usammenhængende karakter 27, 28, hvilket gør det en attraktiv mulighed for coukrølle med DSC (såvel som OPV). TTA-UC er blevet demonstreret i drift ved relativt lave lysintensiteter og i diffuse lysforhold. Både DSC og OPV er mest effektive i lav lysintensitet regime. Solar koncentration er dyrt og kun er berettiget til høj effektivitet, høje omkostninger enheder. Den relativt høje ydeevne TTA-UC-systemer i lav intensitet lysforhold kan henføres til den proces, der involverer overfølsomhed chromophorer med stærke, brede absorptionsbånd i koncert med langlivede triplet stater, som er i stand til at diffundere med henblik på at komme i kontakt med interagerende arter . Desuden har TTA-UC vist sig at have høj iboende effektivitet af en kinetisk undersøgelse 26. Selvom TTA-UC opererer ved lav lysintensitet, er der stadig en kvadratisk sammenhæng mellem indfaldende lys intensitet og udsendte lys (mindst ved lave lysintensiteter). Dette skyldes den bimolekylære karakter af processen. For at redegørefor dette og de forskellige eksperimentelle betingelser (især lys intensitet) rapporteret af forskellige grupper, bør en godhedstal systemet (FOM) anvendes til at afmåle ydelsesforbedring tilbydes af opkonvertering. Denne FoM er blevet defineret som ΔJ SC / ʘ, hvor ΔJ SC er stigningen i kortslutningsstrøm (normalt bestemmes ved integration af foton at ladningsbærer Effektivitet, IPCE, med og uden opkonvertering effekt) og ʘ er den effektive sol koncentration (baseret på fotonflux i den pågældende region, der er Q-band absorption af sensibiliserende) 2 29. Heri er en protokol til at producere og korrekt karakteriserer en integreret DSC-TTA-UC-enhed rapporteret, med særlig vægt på potentielle faldgruber i test af enheden. Det er håbet, at dette vil danne grundlag for det videre arbejde på dette område.

integrating a triplet-triplet annihilation up-conversion system to enhance dye-sensitized solar cell response to sub-bandgap light

Den dårlige reaktion dye-sensibiliserede solceller (DSC) til rødt og infrarødt lys er en væsentlig hindring for realiseringen af ​​en højere fotostrømme og dermed højere effektivitet. Foton opkonvertering ved hjælp af triplet-triplet udslettelse (TTA-UC) er en attraktiv teknik for at bruge disse ellers spildte lavenergi fotoner til at producere fotostrøm, mens der ikke interfererer med photoanodic ydeevne i en skadelig måde. I forlængelse af dette, TTA-UC har en række funktioner, der adskiller sig fra andre rapporterede foton opkonvertering teknologier, hvilket gør den særligt egnet til kobling med DSC-teknologi. I dette arbejde, en gennemprøvet højtydende TTA-UC-systemet, omfatter en palladium porfyrin sensibilisator og rubrene emitter, er kombineret med en høj ydeevne (DSC udnytte organisk farvestof D149) i en integreret enhed. Enheden viser en forbedret respons på sub-båndgab lys over absorptionen vifte af TTA-UC underenhed resulterer i den højeste figur af merit for opkonvertering assisteret DSC hidtidige resultater.

Figurer 3A - D display enhancement responser målt under forskellige måleforhold virkningerne diskuteret mere detaljeret nedenfor. Fra de rå løbende forbedringer massefylde bør det være klart, at resultaterne i figur 4A og 4B kan henføres til opkonvertering med spidsstrømmen forbedring og IPCE forbedring matcher godt med absorptionsspektret af sensibilisator, svækket ved transmission gennem det aktive lag af DSC.
