In this paper, we demonstrate new electrode pattern on rear side of p-type bifacial passivated emitter and rear cells (bifacial-PERC) solar cells for reducing series resistance loss caused by the aluminum grid lines. Cell efficiency of bifacial PERC is enhanced by rear Al grids add multi bus-bar (MBB) or grid segments interconnection. The high J(sc) and FF value of the PERC+ using local grid with MBB as rear electrodes which increases the J(sc) by 0.5 mA/cm(2) and FF by 2.58 % compare to the PERC+ without rear MBB. The high Jsc and FF value of the PERC+ using local grid with vertical line segments as rear electrodes which increases the J(sc) by 0.34 mA/cm(2) and FF by 3.6 % compare to the PERC+ without vertical line segments. In contrast to the PERC cell, the bifacial PERC cell using localized Al grid on rear side and with thicker back surface field (BSF).
