Zinc tin oxide as high-temperature stable recombination layer for mesoscopic perovskite/silicon monolithic tandem solar cells

Christophe Ballif, Davide Sacchetto, Xavier Niquille, Arnaud Walter, Stefaan De Wolf, Sylvain Nicolay, Oscar Esteban Rucavado Leandro, Björn Niesen, Monica Morales Masis, Soo-Jin Moon

Perovskite/crystalline silicon tandem solar cells have the potential to reach efficiencies beyond those of silicon single-junction record devices. However, the high-temperature process of 500 °C needed for state-of-the-art mesoscopic perovskite cells has, ...

Organic-inorganic halide perovskite/crystalline silicon four-terminal tandem solar cells

Christophe Ballif, Sylvain Nicolay, Jun Ho Yum, Stefaan De Wolf, Martin Ledinsky, Björn Niesen, Julien Claude Bailat, Soo-Jin Moon

Tandem solar cells constructed from a crystalline silicon (c-Si) bottom cell and a low-cost top cell offer a promising way to ensure long-term price reductions of photovoltaic modules. We present a four-terminal tandem solar cell consisting of a methyl amm ...

Complex Refractive Index Spectra of CH3NH3PbI3 Perovskite Thin Films Determined by Spectroscopic Ellipsometry and Spectrophotometry

Christophe Ballif, Jun Ho Yum, Stefaan De Wolf, Björn Niesen, Soo-Jin Moon, Michael Elias Stückelberger, Jérémie Werner

The complex refractive index (dielectric function) of planar CH3NH3PbI3 thin films at room temperature is investigated by variable angle spectroscopic ellipsometry and spectrophotometry. Knowledge of the complex refractive index is essential for designing ...

Sputtered rear electrode with broadband transparency for perovskite solar cells

Christophe Ballif, Arnaud Walter, Stefaan De Wolf, Sylvain Nicolay, Björn Niesen, Jérémie Werner, Monica Morales Masis, Soo-Jin Moon, Philipp Friedrich Hermann Löper, Guy Joseph Günter Dubuis

Due to their high efficiencies combined with simple and cost-effective device fabrication, perovskite solar cells are promising candidates as top cells in tandem devices. For this application, the perovskite solar cell must be highly transparent at near-in ...

Raman Spectroscopy of Organic-Inorganic Halide Perovskites

Christophe Ballif, Jun Ho Yum, Jakub Holovsky, Stefaan De Wolf, Martin Ledinsky, Björn Niesen, Soo-Jin Moon

Micro-Raman spectroscopy provides laterally resolved microstructural information for a broad range of materials. In this Letter, we apply this technique to tri-iodide (CH3NH3PbI3), tribromide (CH3NH3PbBr3), and mixed iodide-bromide (CH3NH3PbI3-xBrx) organi ...

Laser-Scribing Patterning for the Production of Organometallic Halide Perovskite Solar Modules

Christophe Ballif, Jun Ho Yum, Arnaud Walter, Sylvain Nicolay, Laurent Fabien Hubert Sansonnens, Julien Claude Bailat, Soo-Jin Moon, Mustapha Benkhaira

Efficiencies of solar cells based on organometallic halide perovskite absorber material have dramatically increased over the past few years. Most of efficiencies reported so far have, however, been obtained on solar cells with very small lab-scale area of ...

4,9-Dihydro-4,4,9,9-tetrahexyl-s-indaceno[1,2-b:5,6-b ']dithiophene as a pi-Spacer of Donor-pi-Acceptor Dye and Its Photovoltaic Performance with Liquid and Solid-State Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Robin Humphry-Baker, Thomas Moehl, Soo-Jin Moon

A new D-pi-A organic dye, LC-5, containing 4,9-dihydro-4,4,9,9-tetrahexyl-s-indaceno[1,2-b:5,6-b']-dithiophene as a novel pi-conjugated spacer has been synthesized and tested as a sensitizer in dye-sensitized solar cells (DSC). Volatile and ionic liquid el ...

Determining the Conductivities of the Two Charge Transport Phases in Solid-State Dye-Sensitized Solar Cells by Impedance Spectroscopy

Michael Graetzel, Shaik Mohammed Zakeeruddin, Soo-Jin Moon, Nripan Mathews, Feng Li

To apply impedance spectroscopy (IS) for studying charge transport in the mesoporous film of solid-state dye-sensitized solar cells (ss-DSCs), it is necessary to determine the relative conductivities of the electron and hole transporting phases, given the ...
