1. A solar cell module comprising:
a plurality of solar cells that are arranged in an array, the solar cells each having a light receiving surface;
an encapsulant that encapsulates the solar cells; and
a backsheet comprising a material, the backsheet on a back portion of the solar cell module, the material of the backsheet comprising a continuous reflective portion, the continuous reflective portion being configured to reflect light coming from a front portion of the solar cell module, the continuous reflective portion being continuous and disposed between the solar cells and a plurality of transparent portions, which are coplanar with the continuous reflective portion, which comprise material of the backsheet, and which are within spaces defined by the continuous reflective portion,
wherein light coming from the back portion of the solar cell module passes through the transparent portions of the backsheet.
