Scire, D. (author), Macaluso, Robert (author), Mosca, Mauro (author), Mirabella, S. (author), Gulino, Antonino (author), Isabella, O. (author), Zeman, M. (author), Crupi, I. (author)Thin layers of MoO<sub>x</sub> have been deposited by thermal evaporation followed by post-deposition annealing. The density of states distributions of the MoO<sub>x</sub> films were extracted deconvoluting the absorption spectra, measured by a photothermal deflection spectroscopy setup, including the small polaron contribution. Results...journal article 2021

Rezaei, N. (author), Isabella, O. (author), Vroon, Zeger (author), Zeman, M. (author)A 3-D optical modelling was calibrated to calculate the light absorption and the total reflection of fabricated CIGS solar cells. Absorption losses at molybdenum (Mo) / CIGS interface were explained in terms of plasmonic waves. To quench these losses, we assumed the insertion of a lossless dielectric spacer between Mo and CIGS, whose optical...journal article 2018

Vismara, R. (author), Isabella, O. (author), Zeman, M. (author)We present the optical investigation of a novel back-contacted architecture for solar cells based on a thin barium (di)silicide (BaSi<sub>2</sub>) absorber. First, through the analysis of absorption limits of different semiconducting materials, we show the potential of BaSi<sub>2</sub> for photovoltaic applications. Then, the proposed back...journal article 2017
