Metoderne i dette værk beskriver fremstillingen af ​​effektive nanofibre fotoanoder til fotokatalytiske indretninger, såsom DSSC&#39;er. Elektrospinning er en meget alsidig teknik til fremstilling af nanofibre, men en vis grad af færdighed og viden er nødvendig for at opnå materialer med optimale morfologier. Et af de mest kritiske aspekter ved opnåelse af gode nanofibre er fremstillingen af ​​precursoropløsningen: der er nogle nøglefaktorer, såsom koncentrationen af ​​bærerpolymeren og valget af t...

Farvefølsomme solceller (DSSC&#39;er) er et interessant alternativ til siliciumbaserede solceller 1 takket være deres lave omkostninger, relativt enkle produktionsprocesser og lethed i storskala produktion. En anden fordel er deres potentiale at blive inkorporeret i fleksible substrater, en klar fordel over siliciumbaserede solceller 2 . En typisk DSSC udnytter: (1) en nanopartikulær TiO 2- fotoanode, sensibiliseret med et farvestof som et lyshøstende lag; (2) en Pt-belagt FTO, der anvendes som en counter elektrode; Og (3) en elektrolyt indeholdende et redoxpar, såsom I - / I3 - , placeret mellem de to elektroder, arbejder som et &quot;hulledende medium&quot;. Selv om DSSC&#39;er har overgået effektiviteten på 15% 3 , er præstationen af ​​nanopartikelbaserede fotanoder stadig stadig hindret af en række begrænsninger, herunder langsom elektron mobilitetY 4 , dårlig absorption af lavenergifotoner 5 og opladning af rekombination 6 . Elektronindsamlingseffektiviteten afhænger stærkt af hastigheden af ​​elektrontransport gennem Ti02-nanopartiklerlaget. Hvis ladningsdiffusionen er langsom, øges sandsynligheden for rekombination med I3 - i elektrolytopløsningen, hvilket resulterer i tab af effektivitet. Det har vist sig, at udskiftning af nanopartikulært Ti02 med endimensionale (1D) Ti02-nanoarkitekturer kan forbedre ladningstransporten ved at reducere spredningen af ​​frie elektroner fra korngrænserne for de indbyrdes forbundne TiO2 nanopartikler 7 . Da 1D nanostrukturer giver en mere direkte vej til opladning, kan vi forvente, at elektrontransport i nanofibre (NF&#39;er) ville være betydeligt hurtigere end i nanopartikler 8 , </sup&gt; 9 . Elektrospinning er en af ​​de mest almindeligt anvendte metoder til fremstilling af fibrøse materialer med submikrondiametre 10 . Denne teknik indebærer anvendelsen af ​​højspænding til at inducere udstødningen af ​​en polymeropløsningsstråle gennem en spindel. På grund af bøjningsstabilitet strækkes denne stråle derefter mange gange for at danne kontinuerlige nanofibre. I de senere år har denne teknik været anvendt i vid udstrækning til fremstilling af polymere og uorganiske materialer, der er blevet anvendt til talrige og forskellige anvendelser, såsom vævsteknik 11 , katalyse 12 og som elektrodematerialer til lithiumionbatterier 13 og superkapacitorer 14 . Anvendelsen af ​​elektrospun TiO 2 -NF&#39;er som spredningslaget i fotoanoeden kan øge DSSC&#39;ernes ydeevne. Imidlertid fotoanoder med nanofibroOs arkitekturer har en tendens til at have dårlig absorption af farvestoffer som følge af overfladeareal begrænsninger. En af de mulige løsninger til at overvinde dette er at blande NF&#39;er og nanopartikler. Dette har vist sig at resultere i yderligere spredningslag, hvilket forbedrer lysabsorptionen og den samlede effektivitet 15 . Protokollen præsenteret i denne video giver en let metode til at syntetisere ultralong TiO 2 nanofibre gennem en kombination af elektrospinning og sol-gel teknikker, efterfulgt af en calcineringsproces. Protokollen illustrerer derefter anvendelsen af ​​Ti02 -NF&#39;erne i kombination med nanopartikulært TiO2 til fremstilling af en dobbeltlagsfotoanode med forbedret lysfordelingskapacitet ved anvendelse af lægemidleteknikteknikker såvel som den efterfølgende samling af en DSSC under anvendelse af en sådan photoanode.

electrospinning of photocatalytic electrodes for dye-sensitized solar cells

Dette arbejde demonstrerer en protokol til fremstilling af en fiberbaseret photoanode til farvesensibiliserede solceller, der består af et lysdisplaylag lavet af elektrospun titandioxid nanofibre (TiO 2 -NF&#39;er) oven på et blokeringslag lavet af kommercielt tilgængelig titandioxid Nanopartikler (Ti02-NP&#39;er). Dette opnås ved først at elektrospinning en opløsning af titan (IV) butoxid, polyvinylpyrrolidon (PVP) og iseddikesyre i ethanol for at opnå sammensatte PVP / Ti02 nanofibre. Disse kalcineres derefter ved 500 ° C for at fjerne PVP og for at opnå rene anatasefase titanoxid nanofibre. Dette materiale er karakteriseret ved anvendelse af scanningselektronmikroskopi (SEM) og pulverrøntgendiffraktion (XRD). Fotoanoeden fremstilles ved først at skabe et blokeringslag gennem aflejringen af ​​en TiO2-NPs / terpineolopslæmning på en fluordoteret tinoxid (FTO) glasskinne ved anvendelse af lægemiddelsøgningsteknikker. En efterfølgende termisk behandlingUdføres ved 500 ° C. Derefter dannes lysdisspredningslaget ved at deponere en TiO2 -NFs / terpineolopslæmning på samme dias ved anvendelse af den samme teknik og kalcinere igen ved 500 ° C. Udførelsen af ​​fotoanoderen testes ved at fremstille en farvestof-sensibiliseret solcelle og måle dens effektivitet gennem JV-kurver under en række indfaldende lysdensiteter fra 0,25-1 søn.

TiO2 nanofibrene blev karakteriseret ved anvendelse af SEM, røntgenfotoelektron-spektroskopi (XPS) og XRD. Nanoostrukturen af ​​fotoanoeden blev karakteriseret ved anvendelse af SEM. Udførelsen af ​​den samlede DSSC blev testet ved hjælp af en solsimulator og en kildeenhedsenhed. SEM-billedet i figur 1A viser, at nanofibrene syntetiseret under anvendelse af denne protokol har en porøs ...
