Electrical parameters of solar cells with electrodes made by selective metallization

Purpose – This paper aims to present the results of measurements of the photovoltaic structures made by electroless selective metallization technology. The developed technology provides low-cost contacts in any form, and parameters of photovoltaic cells made in this technology provide reliable results, comparable with those usually used. Design/methodology/approach – In this paper, photovoltaic cells with contacts based on Nip and NiCuP alloy were performed. As a substrate, mono- and multicristaline silicon was used. After photovoltaic cells have been prepared, sheet resistance of the contact layers and electrical parameters were measured. Composition and structure of contact layers were also measured. Findings – Obtained results of sheet resistance and contact layers are repeatable and comparable with previously published results. Electrical parameters of the photovoltaic cells made are comparable with used substrate and technologies. The authors have also noticed that the costs of the electroless metall...
