Denne protokollen gir et middel for å oppnå foton opp-konvertering forbedret DSC og detaljer på hvordan du skal måle en slik enhet. FOM gir mulighet for enkel beregning av forventede ΔJ SC forbedringer som kan forventes på forskjellige lysintensitet, også på en søndag. Verdiene vist her er invariant med lysintensiteten (innfelt i figur 4), i henhold til forventning når systemet er under sitt metningsterskelen 33. Med FOM, kan vi standardisere forsterkningseffekten av TTA-...

Dye-sensibiliserte solceller (DSCS) har blitt kunngjort som en lovende konsept i rimelig solenergi samling 1-3. Til tross for dette entusiasme, har utbredt kommersialisering ennå ikke forekomme. En rekke årsaker har det blitt fremsatt for dette, med en trykke problemet blir den relativt høye energien fra absorpsjonen innsettende, begrenser oppnåe lys høsting effektiviteten av disse enhetene 4. Selv om dette kan overvinnes, senke absorpsjonen utbruddet blir vanligvis ledsaget av et fall i spenning ved åpen krets, som uforholdsmessig eroderer eventuelle gevinster i strømtetthet 5, 6. Den generelle drift av DSCs omfatter elektronoverføring fra en photoexcited fargestoff til en halvleder (typisk TiO 2), fulgt av regenerering av den oksiderte fargestoffet av en redoks-mediator. Begge disse prosessene ser ut til å kreve betydelige drivkrefter (potensielle) for å fortsette med høy effektivitet 7 </sup&gt;. Med slike vesentlige iboende tap, blir det tydelig at den optimale absorpsjon utbruddet for disse enhetene er rimelig høy i energi. Lignende problemer eksisterer for organiske solceller (OPV), pga igjen til de store kjemiske drivkrefter som kreves for effektiv ladningsseparasjon. Følgelig spådommer om øvre solar-til-elektrisk konvertering effektivitet grenser for enkeltkoblings enheter basert på begge disse teknologiene involvere dempere med brede (effektiv) bandet fire hullene. For å overvinne den lette høsting problemet hevet ovenfor, har en rekke tilnærminger blitt tatt. Dette inkluderer den &quot;tredje generasjon&quot; 8 tilnærminger av tandem strukturer 9, 10 og fotonet oppskalering 11-14. Nylig 11 vi rapporterte en integrert enhet bestående av en DSC arbeids-og motelektroden, med en triplett-trip utslettelse basert up-konvertering (TTA-UC) system tatt itil strukturen. Dette TTA-UC elementet var i stand til å høste rødt lys som overføres gjennom det aktive laget og kjemisk omdanne den (som beskrevet i detalj nedenfor) til høyere energi fotoner som kan bli absorbert av det aktive laget av DSC og generere photo. Det er to viktige punkter å merke seg om dette systemet. For det første har TTA-UC mange potensielle fordeler fremfor andre fotonet oppskalering systemer 11; for det andre viser en mulig arkitektur (proof-of-prinsippet) for inkorporering av TTA-UC, som hadde vært mangler fra TTA-UC litteratur opp til det punktet. Prosessen med TTA-UC 15-24 innebærer eksitering av &quot;sensibiliserende&quot; molekyler, i dette tilfellet Pd porfyriner, av lys med energi under apparatets utbruddet energi. Singlet-excited sensibilisatorer gjennomgå raske intersystem krysset til lavest energi triplet tilstand. Derfra kan de overføre energi til en bakke-state triplet-akseptere &#39;emitter &amp; #8217; arter som for eksempel rubren, så lenge overføringen tillates av fri energi 25. Den første triplet tilstand av rubren (T 1) er større enn halvparten av energien i den første spent singtilstand (S 1), men mindre enn halvparten av energien i T 2, noe som betyr at et møte kompleks av to triplet-spent rubrenes kan utslette å gir en singlett-ekssitert emitter molekylet (og den andre i grunntilstanden) med en ganske stor sannsynlighet. Andre stater, statistisk spådd, er mest sannsynlig energisk utilgjengelige for rubren 26. Singlett-ekssitert rubren molekyl kan deretter avgi et foton (fluorescens som per) med energi tilstrekkelig til å eksitere fargestoffet på arbeids-elektrode av DSC. Denne prosess er vist i en animasjon. TTA-UC tilbyr en rekke fordeler sammenlignet med andre UC-systemer, slik som en bred absorpsjon rekkevidde og inkoherent natur 27, 28, noe som gjør det til et attraktivt alternativ for coupling med DSC (samt OPV). TTA-UC har blitt demonstrert i drift ved relativt lave lysintensitet og i diffuse lysforhold. Både DSC og OPV er mest effektive i lav lysintensitet regime. Solar konsentrasjon er kostbare og bare forsvarlig for høy effektivitet, høye kostnader enheter. Den relativt høye ytelsen til TTA-UC-systemer i lav intensitet lysforhold skyldes prosessen involverer Allergi chromophores med sterke, brede absorpsjonsspor i konsert med langlivede triplet stater som er i stand til å spre for å komme i kontakt med samhandlende arter . I tillegg har TTA-UC blitt funnet å ha høy iboende effektivitet fra en kinetisk studie 26. Selv om TTA-UC opererer med lav lysintensitet, er det fortsatt en kvadratisk sammenheng mellom hendelsen lysintensitet og lyset (minst ved lave lysintensitet). Dette er på grunn av den bimolekylære naturen av prosessen. Til kontofor dette, og de varierte eksperimentelle forhold (spesielt lysintensitet) rapportert av ulike grupper, bør en figur av fortjeneste (FOM) systemet benyttes til å måle ytelsen ekstrautstyr tilbys av oppskalering. Denne FOM har blitt definert som ΔJ SC / ʘ, hvor ΔJ SC er økningen i kortslutningsstrøm (vanligvis bestemt av integrering av Incident Photon Lade Carrier Effektivitet, IPCE, med og uten oppskalering effekt) og ʘ er den effektive solenergi konsentrasjon (basert på foton fluks i vedkommende region, det vil si Q-bånd absorpsjon av sensibilisator) 2 29. Heri, er en protokoll for å produsere og riktig å karakterisere en integrert DSC-TTA-UC-enhet rapportert, betaler spesiell oppmerksomhet til potensielle fallgruver i enhetstesting. Det er å håpe at dette vil tjene som et grunnlag for videre arbeid på dette feltet.

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

Den dårlig respons av dye-sensitivisert solceller (DSCS) til rødt og infrarødt lys er en betydelig hindring for realisering av høyere photocurrents og dermed høyere effektivitet. Photon up-konvertering ved hjelp av triplett-trip utslettelse (TTA-UC) er en attraktiv teknikk for å bruke disse ellers bortkastet lavenergi fotoner å produsere photo, mens ikke forstyrrer photoanodic ytelse i en skadelig måte. Videre til dette, har TTA-UC en rekke funksjoner, skiller seg fra andre rapporterte foton up-konvertering teknologier, som gjør den spesielt egnet for kopling med DSC-teknologi. I dette arbeidet, et vist høyytelses TTA-UC-system, omfattende en palladium porfyrin sensibilisator og rubren emitter, er kombinert med en høy ytelse DSC (anvendelse av det organiske fargestoff D149) i en integrert enhet. Enheten viser en forbedret respons på sub-bandgap lys over absorpsjonsområdet på TTA-UC underenhet som resulterer i den høyeste figur of Merit for opp-konvertering assistert DSC ytelse til dato.

Figurer 3A - D skjerm enhancement responser målt under forskjellige måleforholdene, med effekten diskutert i mer detalj nedenfor. Fra de rå strømtetthet forbedringer bør det være klart at resultatene i figur 4A og 4B er tilordnet oppskalering, med toppspenningen ekstrautstyr og IPCE forsterkning stemte godt med absorbsjons-spekteret av sensibilisator, dempes ved overføring gjennom det aktive sjikt av DSC.

Integrating a Triplet-triplet Annihilation Up-conversion System to Enhance Dye-sensitized Solar Cell Response to Sub-bandgap Light

En integrert enhet, som omfatter en dye-sensitivisert solcelle og triplet-triplet utslettelse up-konvertering enhet ble produsert, affording forbedret lys høsting, fra et bredere delen av solspekteret. Under beskjedne bestrålingsnivå en betydelig forbedret respons på lavenergi fotoner ble demonstrert, noe som gir en rekord figur av fortjeneste for dye-sensibiliserte solceller.
