| 1. A bifacial solar cell module comprising:
a plurality of solar cells;
an encapsulant that encapsulates the plurality of solar cells;
a transparent top cover on a front portion of the bifacial solar cell module; and
a backsheet on a back portion of the bifacial solar cell module, the backsheet having transparent portions that expose backsides
of the plurality of solar cells as viewed from the back portion and that allow light coming from the back portion of the bifacial
solar cell module to enter through the transparent portions, the backsheet having an integrated reflective portion that reflects
light coming from the front portion of the bifacial solar cell module, the backsheet being an outermost packaging component
on the back portion of the bifacial solar cell module,
wherein the integrated reflective portion is continuous and the transparent portions are formed coplanar with the integrated
reflective portion and within spaces defined by the integrated reflective portion.
