[1] Bifacial concentrator n-type (biconty) crystalline silicon ag-free solar cell / G. G. Untila, T. N. Kost, A. B. Chebotareva et al. // Proceedings 28th European Photovoltaic Solar Energy Conference. — WIP-Munich Munich, 2013. — P. 583–586. Results obtained for the bifacial low concentrator Ag free Cz silicon solar cells based on Indium-Tin-Oxide(ITO)/(p+nn+)Cz-Si/Indium-Fluorine-Oxide (IFO) structure are presented in this work. The (p+nn+)Cz-Si structure was produced by diffusion of boron and phosphorus from deposited B- and P-containing glasses followed by an etch-back step. The n+ surface of the structures was textured, whereas the p+ surface remained planar. Transparent conducting oxide (TCO) films, which act as passivating and antireflection electrodes, were deposited by ultrasonic spray pyrolysis method on both sides. The contact pattern of copper wire was attached by the lowtemperature (160oC) lamination method simultaneously to the front and rear TCO layers as well as to the interconnecting ribbons arranged outside the structure. The shadowing from the contacts is in the range of ∼4%. The resulting solar cells showed front/rear efficiencies of 17.3–17.7%/18.1–18.5% at 1–5 suns. Even at 1 sun rear illumination and 20–50% 1-sun front illumination, such a cell will generate energy approaching that produced by a monofacial solar cell of 21.6-26.8% efficiency. [ DOI ]
