Journal ArticleDOI
Synthesis of mesoporous titanium dioxide by soft template based approach: characterization and application in dye-sensitized solar cells
Satyanarayana Reddy Gajjela,Krishnamoorthy Ananthanarayanan,Christopher Yap,Michael Grätzel,Palani Balaya +4 more
TL;DR: In this article, a soft-template-directed approach was used to prepare mesoporous titanium dioxide and apply it in dye-sensitized solar cells (DSSCs).
Journal ArticleDOI
Deposition of hole-transport materials in solid-state dye-sensitized solar cells by doctor-blading
I-Kang Ding,John Melas-Kyriazi,Ngoc-Le Cevey-Ha,Kethinni G. Chittibabu,Shaik M. Zakeeruddin,Michael Grätzel,Michael D. McGehee +6 more
TL;DR: In this paper, a roll-to-roll compatible, large-area coating technique, called doctor-blading, was used to replace conventional spin coating for the deposition of the hole-transport material spiro-OMeTAD (2,2',7,7'-tetrakis-(N,Ndi-p-methoxyphenylamine)-9,9'-spirobifluorene) in solid-state dye-sensitized solar cells.
Journal ArticleDOI
Passivation of nanocrystalline TiO2 junctions by surface adsorbed phosphinate amphiphiles enhances the photovoltaic performance of dye sensitized solar cells
TL;DR: It is demonstrated that co-adsorption of dineohexyl bis-(3,3-dimethyl-butyl)-phosphinic acid along with the amphiphilic ruthenium sensitizer Z907Na increased substantially the power output of the cells mainly due to a retardation of interfacial recombination of photo-generated charge carriers.
Journal ArticleDOI
The Role of Insulating Oxides in Blocking the Charge Carrier Recombination in Dye-Sensitized Solar Cells
TL;DR: In this article, a complete photovoltaic study is done by depositing different cycles (by ALD) of four different insulating oxides (Ga2O3, ZrO2, Nb2O5, and Ta2O4) and their recombination characteristics, surface electronic properties, transport rate, and injection dynamics are investigated with a standard organic dye and Co2+/Co3+ redox mediator.
Journal ArticleDOI
Optical analysis of CH3NH3SnxPb1–xI3 absorbers: a roadmap for perovskite-on-perovskite tandem solar cells
Miguel Anaya,Juan P. Correa-Baena,Gabriel Lozano,Michael Saliba,Pablo Martínez de Anguita,Bart Roose,Antonio Abate,Ullrich Steiner,Michael Grätzel,Mauricio E. Calvo,Anders Hagfeldt,Hernán Míguez +11 more
TL;DR: In this paper, a user's guide based on the first set of optical constants obtained for a series of tin/lead perovskite films, which was only possible to measure due to the preparation of optical quality thin layers.
