Embodiment Construction
[0026] see figure 1 , figure 1 It is a sectional view of the appearance of the flexible solar cell module 10 according to the embodiment of the present invention. The flexible solar cell module 10 includes a flexible insulating plate 12 and a plurality of solar cells 101 . The flexible insulating plate 12 is a flexible thin plate, and a plurality of solar cells 101 are arranged at intervals on the flexible insulating plate 12, wherein the flexible insulating plate 12 can be ethylene vinyl acetate copolymer (Ethylene Vinyl Acetate, EVA ) or polyimide (Polyimide, PI) and other insulating compounds. The solar cell 101 can be a generally known simple solar cell, and the solar cell 101 includes a substrate 14 disposed on a flexible insulating plate 12; a first electrode layer 16 formed on the substrate 14; a photoelectric conversion Layer 18, formed on the surface of the first electrode layer 16 and part of the first electrode layer 16 exposed at both ends, that is, the width of...

A flexible solar battery module includes a flexible insulating base and a plurality of solar batteries separately disposed on the flexible insulating base. The solar battery includes a substrate disposed on the flexible insulating base, a first electrode disposed on the substrate, a photoelectric transducing layer disposed on the first electrode and exposing parts of the first electrode, and a second electrode disposed on the photoelectric transducing layer. The flexible solar battery module further includes an insulating layer disposed on the exposed first electrode of each solar battery and the exposed flexible insulating base between the adjacent solar batteries, and an auxiliary electrode disposed on the second electrode of each solar battery and the exposed first electrode of the adjacent solar battery for setting the plurality of solar batteries in a series connection.
Description
technical field [0001] The invention relates to a solar battery module, in particular to a flexible solar battery module and a manufacturing method thereof. Background technique [0002] A conventional flexible solar cell module includes a plurality of solar cells with a metal thin plate as a substrate, and the upper electrode layer of the solar cell is extended to the metal substrate of an adjacent solar cell to overlap the plurality of solar cells. connected in series, the disadvantage of this series method is that the upper electrode layer and absorber layer of the solar cell are easily broken and broken because they cannot bear the pressure generated when the metal substrate is bent, which will seriously affect the flexible solar cell. The photoelectric conversion efficiency of the module, and this series connection will cause the aperture ratio of the flexible solar cell module to be too low, which cannot provide the optimal photoelectric conversion efficiency, such as ...
