Autor: A. Le Donne, S. Marchionna, P. Garattini, R. A. Mereu, M. Acciarri, S. Binetti

Publikováno v: International Journal of Photoenergy, Vol 2015 (2015)

Cu2ZnSnS4 (CZTS) absorber layers grown by sputtering were investigated by photoluminescence before and after the chemical bath deposition of CdS in order to evaluate the possible passivation of point defects by Cd atoms at the absorber/buffer layer i

The missing piece: The Ti3C2Tx MXene structure and its role in the outstanding reversibility as negative electrode in sodium ion batteries

Autor: Irene Quinzeni, Giovanni Maria Vanacore, Simone Pollastri, Antonio Gentile, Paolo Ghigna, Martina Fracchia, Clemens Ritter, Chiara Ferrara, S. Marchionna, Riccardo Ruffo

This study proposes the full structural characterization of the most common MXene composition, Ti3C2Tx, which presents outstanding stability as anode for sodium ion batteries (100% of capacity retention after 530 cycles with charge efficiency > 99.7%

'Nano Letters ', vol: 21, pages: 8290-8297 (2021)

The most common MXene composition Ti3C2Tx(T = F, O) shows outstanding stability as anode for sodium ion batteries (100% of capacity retention after 530 cycles with charge efficiency >99.7%). However, the reversibility of the intercalation/deintercala

Design and characterization of a chloride-free organic copper solution: Electrochemical synthesis of Zn/Cu/Sn precursor stack for CZTS-based photoconversion devices

Autor: Luca Magagnin, S. Marchionna, Simona Binetti, Maurizio Acciarri, Ruben Dell'Oro, Gabriele Panzeri, Jacopo Parravicini, Maurizio Sansotera

In the present study, an ethylene glycol-based electrolyte is used to electrodeposit copper onto zinc for the synthesis of the Zn/Cu/Sn stack, precursor of Cu2ZnSnS4. The employed solution contains diethanolamine (DEA) which supports the formation of

Ti3C2Tx MXene compounds for electrochemical energy storage

Autor: Antonio Gentile, Riccardo Ruffo, Chiara Ferrara, S. Marchionna

Publikováno v: Current Opinion in Electrochemistry. 29:100764

Since their discovery in 2011, MXene compounds, and in particular the Ti3C2-based phases, have gained increasing interest from researchers leading to over 2000 scientific works in 2020. The peculiar morphological, charge transport, and surface proper

Growth of Cu2MnSnS4 PV absorbers by sulfurization of evaporated precursors

Autor: S. Marchionna, Marco Merlini, A. Le Donne, Maurizio Acciarri, F. Cernuschi, Simona Binetti

Publikováno v: Journal of Alloys and Compounds. 693:95-102

Earth abundant Cu2MnSnS4(CMTS) absorbers for thin film solar cells were grown for the first time by a two-step vacuum approach. Metal precursors deposited on Mo-coated soda lime glass by thermal evaporation were annealed in sulfur vapors. Two series
