[1] Bifacial concentrator ag-free crystalline n-type si solar cell / G. G. Untila, T. N. Kost, A. B. Chebotareva et al. // Progress in Photovoltaics: Research and Applications. — 2015. — Vol. 23, no. 5. — P. 600–610. We report results obtained using an innovative approach for the fabrication of bifacial low-concentrator thin Ag-free n-type Cz-Si (Czochralski silicon) solar cells based on an indium tin oxide/(p+nn+)Cz-Si/indium fluorine oxide structure. The (p+nn+)Cz-Si structure was produced by boron and phosphorus diffusion from B- and P-containing glasses deposited on the opposite sides of n-type Cz-Si wafers, followed by an etch-back step. Transparent conducting oxide (TCO) films, acting as antireflection electrodes, were deposited by ultrasonic spray pyrolysis on both sides. A copper wire contact pattern was attached by low-temperature (160oC) lamination simultaneously to the front and rear transparent conducting oxide layers as well as to the interconnecting ribbons located outside the structure. The shadowing from the contacts was ∼4%. The resulting solar cells, 25 × 25mm2 in dimensions, showed front/rear efficiencies of 17.6–17.9%/16.7–17.0%, respectively,at one to three suns (bifaciality of ∼95%). Even at one-sun front illumination and 20–50% one-sun rear illumination, such a cell will generate energy approaching that produced by a monofacial solar cell of 21–26% efficiency. [ DOI ]
