PURPOSE:To possible make easy attachment and detachment of a submodule by arraying recesses formed in a protective resin layer which fills gaps of unit solar cells series-connected by connection conductors or through holes which penetrate the protective resin layer and a flexible substrate. CONSTITUTION:The exposure face side of a transparent plastic film 1 is overlapped with a front protective film 4, and the lead wire 3 side with a rear protective film 5 via an insulating resin 6 to sandwich a photoelectric conversion layer, and an equivalent of submodule 2 is fed to laminate one after another. Through holes 7 of 0.5mm width and 5mm length are punched out by press at 1cm-intervals out of a film 1 along with both side films 4, 5 and an insulating resin layer 6 between adjacent submodules 2 to form so that a lead wire 3 may not overlap a through hole 7. Therefore, it becomes easy to cut out only the submodule 2 in a defective part with a cutter or the like along a through hole 7, and to fill a gap with a non-defective article, so that a thin film solar cell having a long flexible substrate can be repaired easily. |
