“…The LGCell efficiency was 17.6% under front side illumination and 16.7% under rear side illumination (bifaciality of 95%). At 20–50% of one‐sun rear illumination, such a cell will generate energy approaching that produced by a monofacial solar cell of 21–26% efficiency .…”

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 (160°C) 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 × 25 mm 2 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.

“…The performance of bifacial PV cell in different static solar concentrator has been analyzed by many authors [10][11][12][13]. By incorporating the bifacial cells in fixed non-imaging concentrators, he achieved up to seven times the annual energy output of equal area of monofacial cells in flat panels.…”

This paper depicts the electrical performance of the bifacial PV module at multiple sun conditions. The integration of the bifacial module into a new static Sea Shell concentrator have been accomplished to take the benefits from a large range of acceptance angle (+36° to -36°) and an average optical gain 2.815. The dependency of the short circuit current (Isc), maximum power output (Pm), and efficiency (η) on the incident angle of illumination and optical gain of the concentrator have been analyzed in this manuscript. Simulation of the performance parameters of the bifacial module has been accomplished to estimate the average electrical output from summer to winter solstice. It has been possible to obtain more than 180 % enhancement in Isc, 250 % in Pm , and 35 % in η from the rear surface of the module when integrated into Sea Shell concentrator. The effect of the series resistance (Rs) on the Pm and η of the bifacial PV module has also been reported.

“…However, at the present find that thermal diffusion of impurity atoms in silicon is of interest both from the scientific point of view and due to the cheapness of the process. The low cost of thermal diffusion is very important for manufacturing of solar elements [1,2,3,4,5,6,7] and other semiconductor devices. Thermal diffusion is also used for the gettering of undesirable impurities such as iron [8,9,10].…”
