(author), Mazzarella, L. (author), Isabella, O. (author)Passivating contacts are crucial for realizing high-performance crystalline silicon solar cells. Herein, contact formation by plasma-enhanced chemical vapor deposition (PECVD) followed by an annealing step is focused on. Poly-SiO<sub>x</sub> passivating contacts by combining plasma-assisted N<sub>2</sub>O-based oxidation of silicon (PANO-SiO...journal article 2023

(author), Yao, Z. (author), Zeman, M. (author), Santbergen, R. (author), Mazzarella, L. (author), Isabella, O. (author)Thin films of transition metal oxides such as molybdenum oxide (MoO<sub>x</sub>) are attractive for application in silicon heterojunction solar cells for their potential to yield large short-circuit current density. However, full control of electrical properties of thin MoO<sub>x</sub> layers must be mastered to obtain an efficient hole...journal article 2022

(author), Zeman, M. (author), Isabella, O. (author)Excellent surface passivation induced by (i)a-Si:H is critical to achieve high-efficiency silicon heterojunction (SHJ) solar cells. This is key for conventional single-junction cell applications but also for bottom cell application in tandem devices. In this study, we investigated the effects of (i)a-Si:H deposition temperature on passivation...journal article 2022

(author)The effect of thermal aging of homogenized Fe-Au and Fe-Au-W alloys, irradiated at room temperature with hydrogen ions, was studied for an aging treatment at 300 °C for aging times up to 100 h. The aging behavior of the Fe-based alloys is compared to the results for pure Fe. The precipitation behavior of Au-rich and W-rich precipitates and...journal article 2021
