För att utnyttja molekylens bulkighet i denna metod är det viktigt att känna till villkoren för filmbildning genom spinnbeläggning. För det första måste de av p-typ och n-typ halvledare kunna lösas i lösningsmedlen. När en del material kvarstår, kommer det att bli den stora kärnan av domänerna i den fotoaktiva skiktet. Användningen av en lämplig kommersiell filter för enskilda lösningsmedel rekommenderas att ta bort det återstående materialet. Sedan måste prekursorlösningen i vilken molekylerna upp...

Organiska fotogalvaniska anordningar anses lovande förnybara energikällor på grund av deras låga tillverkningskostnader och låg vikt 1-7. På grund av dessa fördelar, har ett stort antal forskare varit nedsänkt i detta lovande område. Under det senaste decenniet, färgkänslig, har organiska tunnfilms och perovskit solceller gjort betydande framsteg i effektivitet effektomvandling på detta område 8. Specifikt, organiska tunnfilmssolceller och BHJ organiska tunnfilmssolcellsteknik är effektiva och kostnadseffektiva lösningar för utnyttjande av solenergi. Vidare har effektiviteten energiomvandlings nådde över 10% med användning av låg-band-gap-polymerer som elektrondonator och fullerenderivat som elektronacceptor (fenyl-C 61 -smörsyra-Acid-metylester: [60] PCBM eller fenyl-C 71 -smörsyra-syra-metylester: [70] PCBM) 9-11. Dessutom har vissa forskare have redan rapporterade betydelsen av BHJ struktur i den fotoaktiva skiktet, vilken är konstruerad med låg-band-gap polymerer och fullerenderivat för att erhålla en hög total effektivitet. Men fullerenderivat är luftkänsliga. Därför är ett luftstabilt elektronmottagande material som erfordras som ett alternativ. Några rapporter tidigare föreslagits nya typer av organiska solceller som används n-typ halvledande polymerer eller metalloxider som elektronmottagare. Dessa rapporter stött utvecklingen av luftstabila, fullerenfria, organiska tunnfilmssolceller 12-15. Men i motsats till fulleren system eller n-typ halvledande polymersystem, erhållande en tillfredsställande prestanda hos BHJ struktur i den fotoaktiva skiktet, som har laddningsseparation och laddningsöverföringen förmågor, är svårt i metalloxidsystem 16-17. Dessutom fullerenderivat och n-typ halvledande polymerer har hög lösligheti många lösningsmedel. Därför är det lätt att kontrollera morfologin hos det fotoaktiva skiktet genom att välja en färglösning som lösningsmedel, som är föregångaren av det fotoaktiva skiktet 18-20. Däremot i fallet med metallalkoxiden som används i kombination med en elektrondonerande polymer, båda halvledare är olösliga i nästan alla lösningsmedel. Detta beror på att metallalkoxider inte har en hög löslighet i lösningsmedlet. Därför är selektiviteten av lösningsmedel för morfologi kontroll extremt låg. I denna artikel rapporterar vi ett förfarande för att styra morfologin hos den fotoaktiva skiktet genom användning av molekylärt bulkighet att tillverka tryckbara och högt luftstabila BHJ solceller. Vi beskriver vikten av morfologi kontroll för utvecklingen av fullerenfria BHJ solceller.

morphology control for fully printable organic&#8211;inorganic bulk-heterojunction solar cells based on a ti-alkoxide and semiconducting polymer

The photoactive layer of a typical organic thin-film bulk-heterojunction (BHJ) solar cell commonly uses fullerene derivatives as the electron-accepting material. However, fullerene derivatives are air-sensitive; therefore, air-stable material is needed as an alternative. In the present study, we propose and describe the properties of Ti-alkoxide as an alternative electron-accepting material to fullerene derivatives to create highly air-stable BHJ solar cells. It is well-known that controlling the morphology in the photoactive layer, which is constructed with fullerene derivatives as the electron acceptor, is important for obtaining a high overall efficiency through the solvent method. The conventional solvent method is useful for high-solubility materials, such as fullerene derivatives. However, for Ti-alkoxides, the conventional solvent method is insufficient, because they only dissolve in specific solvents. Here, we demonstrate a new approach to morphology control that uses the molecular bulkiness of Ti-alkoxides without the conventional solvent method. That is, this method is one approach to obtain highly efficient, air-stable, organic-inorganic bulk-heterojunction solar cells.

Vi har presenterat ett protokoll för framställning av fullt tryckbara organiska-oorganiska BHJ solceller, liksom ett förfarande för styrning av fasseparation struktur. Den solcells prestanda har undersökts 27-31 när Ti (IV) isopropoxid och etoxid användes som elektronmottagande material (Figur 1). Dessa solceller uppvisade en kortslutningsströmtäthet (Jsc) som är ungefär åtta gånger högre än för enheter som använder &quot;Ti (IV) butoxid polym...
