Yamashita, Yudai (author), Ruiz Tobon, C.M. (author), Santbergen, R. (author), Zeman, M. (author), Isabella, O. (author), Suemasu, Takashi (author)We performed advanced opto-electrical simulations on thin-film BaSi<sub>2</sub> solar cells. First, absorption spectra of BaSi<sub>2</sub>-pn homojunction solar cells on Si substrate were calculated based on flat and/or pyramidally-textured surfaces, wherein 20-nm-thick n<sup>+</sup>-BaSi<sub>2</sub> was the topmost electron transport layer....journal article 2021

Demontis, V. (author), Sanna, C. (author), Melskens, J. (author), Santbergen, R. (author), Smets, A.H.M. (author), Damiano, A. (author), Zeman, M. (author)Thin oxide interlayers are commonly added to the back reflector of thin-film silicon solar cells to increase their current. To gain more insight in the enhancement mechanism, we tested different back reflector designs consisting of aluminium-doped zinc oxide (ZnO:Al) and/or hydrogenated silicon oxide (SiOx:H) interlayers with different metals ...journal article 2013

Schulte, M. (author), Bittkau, K. (author), Jäger, K. (author), Ermes, M. (author), Zeman, M. (author), Pieters, B.E. (author)Textured interfaces in thin-film silicon solar cells improve the efficiency by light scattering. A technique to get experimental access to the angular intensity distribution (AID) at textured interfaces of the transparent conductive oxide (TCO) and silicon is introduced. Measurements are performed on a sample with polished microcrystalline...journal article 2011

Jäger, K. (author), Zeman, M. (author)We present a mathematical model that relates the surface morphology of randomly surface-textured thin films with the intensity distribution of scattered light. The model is based on the first order Born approximation [see e.g., M. Born and E. Wolf, Principles of Optics, 7th ed. (Cambridge University Press, Cambridge, England, 1999) ] and on...journal article 2009
