Photoelectrochemical characterization of squaraine-sensitized nickel oxide cathodes deposited via screen-printing for p-type dye-sensitized solar cells
Screen-printing method has been adopted for the deposition of nickel oxide thin film electrodes with mesoporous features. Nickel oxide was sensitized with three newly synthesized squaraines (VG1C8,VG10C8 and DS2/35) and employed as photoelectroactive cathode of p-type dye-sensitized solar cells. Col...

| description | Screen-printing method has been adopted for the deposition of nickel oxide thin film electrodes with mesoporous features. Nickel oxide was sensitized with three newly synthesized squaraines (VG1C8,VG10C8 and DS2/35) and employed as photoelectroactive cathode of p-type dye-sensitized solar cells. Colorant erythrosine b (EB) was taken as commercial benchmark for comparative purposes. Sensitization was successful with the attainment of overall conversion efficiencies in the order of 0.025% when the mesoporous surface of nickel oxide was alkali treated. The prolongation of nickel oxide sensitization time up to 16h led to a general increase of the open circuit voltage in the corresponding solar cells.

•We deposited nickel oxide with screen-printing technique utilizing nickel oxide nanoparticles.•We employed screen-printed nickel oxide as cathodes of p-DSCs.•We employed new squaraine as sensitizers of screen-printed nickel oxide.•Further progress is expected when the formulation of the screen-printing paste will be optimized.
In the present paper we report on the employment of the screen-printing method for the deposition of nickel oxide (NiOx) layers when preformed nanoparticles of the metal oxide (diameter<50nm) constitute the precursors in the paste. The applicative purpose of this study is the deposition of mesoporous NiOx electrodes in the configuration of thin films (thickness, l≤4μm) for the realization of p-type dye-sensitized solar cells (p-DSCs). Three different squaraine-based dyes (here indicated with VG1C8, VG10C8 and DS2/35), have been used for the first time as sensitizers of a p-type DSC electrode. VG1C8 and VG10C8 present two carboxylic groups as anchoring moieties, whereas DS2/35 sensitizer possesses four acidic anchoring groups. All three squaraines are symmetrical and differ mainly for the extent of electronic conjugation. The colorant erythrosine b (ERY B) was taken as commercial benchmark for the comparison of the different dye-sensitizers. The influence of the conditions of NiOx sensitization and of NiOx surface pre-treatment on the photoelectrochemical performance of the corresponding p-DSCs have been analyzed. The highest overall conversion efficiency achieved within this set of organic colorants was 0.025% with VG1C8 and VG10C8 as colorants when NiOx surface was pre-treated with alkali. The alkaline pre-treatment of the NiO surface led to the highest efficiencies of the incident photon-to-current conversion (IPCEMAX=11% at about 390nm) for the three squaraines here considered in correspondence of the wavelength of their maximum absorption. The prolongation of the sensitization time of NiOx cathodes up to 16h leads to a general increase of the open circuit voltage in the corresponding p-DSCs.</description><identifier>ISSN: 0169-4332</identifier><identifier>EISSN: 1873-5584</identifier><identifier>DOI: 10.1016/j.apsusc.2015.08.171</identifier><language>eng</language><publisher>Elsevier B.V</publisher><subject>Anchoring ; Cathodes ; Deposition ; DSC ; Dyes ; Electrodes ; Nanostructured materials ; Nickel oxide ; Organic sensitizer ; p-type semiconductor ; Pretreatment ; Screen-printing ; Solar cells ; Squaraine ; Surface chemistry</subject><ispartof>Applied surface science, 2015-11, Vol.356, p.911-920</ispartof><rights>2015 Elsevier B.V.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c380t-2f4e403ae63e395fad75d17dee1076470f6f312d870dca398c06224beb17c59b3</citedby><cites>FETCH-LOGICAL-c380t-2f4e403ae63e395fad75d17dee1076470f6f312d870dca398c06224beb17c59b3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0169433215019959$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65534</link.rule.ids></links><search><creatorcontrib>Naponiello, Gaia</creatorcontrib><creatorcontrib>Venditti, Iole</creatorcontrib><creatorcontrib>Zardetto, Valerio</creatorcontrib><creatorcontrib>Saccone, Davide</creatorcontrib><creatorcontrib>Di Carlo, Aldo</creatorcontrib><creatorcontrib>Fratoddi, Ilaria</creatorcontrib><creatorcontrib>Barolo, Claudia</creatorcontrib><creatorcontrib>Dini, Danilo</creatorcontrib><title>Photoelectrochemical characterization of squaraine-sensitized nickel oxide cathodes deposited via screen-printing for p-type dye-sensitized solar cells</title><title>Applied surface science</title><description>Screen-printing method has been adopted for the deposition of nickel oxide thin film electrodes with mesoporous features.
