Publikováno v: Journal of Materials Chemistry A. 8:25283-25289

Organic–inorganic perovskite photovoltaics have now achieved power conversion efficiencies at par with silicon devices on a lab-scale. To enable industrial application of the technology, developing a perovskite deposition route compatible with scal

High-Detectivity Perovskite Light Detectors Printed in Air from Benign Solvents

Autor: Mario Caironi, Giorgio Ferrari, Stefanie Neutzner, Vijay Venugopalan, Annamaria Petrozza, Roberto Sorrentino, Diego Nava, Peter Topolovsek

Summary Here, we propose a simple and low-temperature approach for the synthesis of methylammonium lead halide perovskite inks based on sub-micrometer-sized particles with tunable band gap. The particles allow the formulation of inks in benign solven

Semiconducting transition metal dichalcogenides (TMDs) have been applied as the active layer in photodetectors and solar cells, displaying substantial charge photogeneration yields. However, their large exciton binding energy, which increases with de

Thiol click chemistry on gold-decorated MoS2: elastomer composites and structural phase transitions

Autor: Ales Mrzel, Janez Kovač, Christoph Gadermaier, Luka Cmok, Peter Topolovsek, M. Borovsak

Publikováno v: Nanoscale. 8:10016-10020

We show that gold decorated MoS2 flakes are amenable to thiol chemistry by blending them with a cross-linkable thiolated polysiloxane (PMMS). PMMS prevents restacking of dispersed MoS2 when transforming the metallic to the semiconducting phase. Cross

Interfacial Morphology Addresses Performance of Perovskite Solar Cells Based on Composite Hole Transporting Materials of Functionalized Reduced Graphene Oxide and P3HT

Autor: Luca Perino, Francesco Lamberti, Teresa Gatti, Carla Marega, Gian Andrea Rizzi, Maria Antonietta Loi, Roberto Sorrentino, Leonardo Girardi, Peter Topolovsek, Enzo Menna, Mustapha Abdu-Aguye, Annamaria Petrozza, Marco Salerno

Publikováno v: Solar RRL, 2(5):1800013. John Wiley and Sons Inc.

The development of novel hole transporting materials (HTMs) for perovskite solar cells (PSCs) that can enhance device's reproducibility is a largely pursued goal, even to the detriment of a very high efficiency, since it paves the way to an effective

Functionalization of transparent conductive oxide electrode for TiO2-free perovskite solar cells

Autor: Christoph Gadermaier, Enzo Menna, Teresa Gatti, Peter Topolovsek, James M. Ball, Annamaria Petrozza, A. Cito, Francesco Lamberti

Many of the best performing solar cells based on perovskite-halide light absorbers use TiO2 as an electron selective contact layer. However, TiO2 usually requires high temperature sintering, is related to electrical instabilities in perovskite solar

Low pressure, low temperature synthesis of Mo6S3I6 molecular wires suitable for upscaling

Autor: Dragan Mihailovic, Marina Davydova, Andrej Kovič, Peter Topolovsek

Publikováno v: Synthetic Metals. 162:1677-1680

The possibility of growth of the Mo 6 S 3 I 6 (MoSI) molecular wires under conditions which can be used for large-scale synthesis are investigated. We demonstrate optimum growth of long and thin MoSI wire bundles with Mo metal starting material in na

Femtosecond spectroscopy on MoS2 flakes from liquid exfoliation: surfactant independent exciton dynamics

Autor: Peter Topolovsek, Giulio Cerullo, Tetiana Borzda, Christoph Gadermaier, Iacopo Tempra, Matej Prijatelj, Daniele Vella, Victor Vega-Mayoral, Eva A. A. Pogna, Nataša Vujičić

Ionic surfactants, which are widely used to stabilize nanomaterials in dispersions, can drastically alter the nanomaterial’s photophysical properties. Here, we use femtosecond optical spectroscopy to study the dynamics of excitons and charges in fe

Unlocking the functional properties in one-dimensional MoSI cluster polymers by doping and photoinduced charge transfer

Autor: Dragan Mihailovic, Peter Topolovsek, J. Strle, Christoph Gadermaier, Martin Strojnik, Damjan Vengust

To improve functionalization of MoSI cluster polymers we have studied the effects of adsorption doping on the electrical transport, bundling, and optical absorption spectra. Doping results both in enhanced conductivity and aggregated bundles in dispe

The 2D semiconductor MoS in its mono- and few-layer form is expected to have a significant exciton binding energy of several 100 meV, suggesting excitons as the primary photoexcited species. Nevertheless, even single layers show a strong photovoltaic
