Solar Cell Module having Multiple Module Layers and Manufacturing Method Thereof

A method for manufacturing a solar cell module comprising a bottom module layer for absorbing a greater fraction of light energy in a first wavelength band than in a second wavelength band, the first wavelength band comprising a shorter wavelength than any wavelength in the second wavelength band, the solar cell module also comprising a top module layer formed on the bottom module layer and absorbing a greater fraction of light energy in the second wavelength band than in the first wavelength band, the method comprising:

• forming the bottom module layer on a first substrate, the bottom module layer comprising a plurality of cells serially connected to each other;
• forming a reflecting filter over the bottom module layer, the reflecting filter reflecting a greater fraction of light energy in the first wavelength band than in the second wavelength band and transmitting a greater fraction of light energy in the second wavelength band than in the first wavelength band;
• forming the top module layer on a second substrate, the top module layer comprising a plurality of cells serially connected to each other;
• and
• after forming the bottom module layer and the top module layer, bonding the bottom module layer and the top module layer together by using an EVA sheet.
