PURPOSE:To obtain a solar cell sheet in which the quantity of incident light is increased without loss of its flexibility by utilizing the merit of capability of winding of a flexible substrate, and employing a polymer film in which its face in contact with an air layer is roughed as a window member. CONSTITUTION:A PET film having heat resistance necessary for depositing amorphous silicon and 100mum of thickness is employed as a flexible substrate 21 to form an integrated amorphous solar cell in which three rows of cells 20a are aligned in series. Leads 29a, 29b made of copper foils are attached to both ends of the cells 20a to obtain a solar cell unit sheet 20. Then, a roughed polymer film 40 is laminated as a window member, and a solar cell sheet 20 sealed at its periphery is manufactured. The sheet 10 in which a roughed FET film with ionomer formed with an ionomer layer is laminated on the front side (on the solar cell) of the sheet 20, i.e., window is manufactured. Thus, the output of the flexible solar cell can be improved. |
