An internal series-connected perovskite solar cell module and a preparation method therefor. The perovskite solar cell module comprises a plurality of longitudinally arranged battery sub-packs (1); each battery sub-pack (1) comprises a positive electrode lead-out section (3), a negative electrode lead-out section (4) and a plurality of battery cells (5) which are transversely arranged; and the internal structures of the positive electrode lead-out section (3), the negative electrode lead-out section (4) and the plurality of battery cells (5) respectively comprise, from bottom to top, a substrate (51), a front electrode layer (52), a light absorption layer (53) and a rear electrode layer (54). According to the present invention, the rear electrode layer (54) becomes a connecting wire between the battery sub-packs (1) by means of an appropriate laser scribing process, so as to achieve the effect of connecting the perovskite solar cell module in series to replace traditional busbars, thereby greatly reducing the use of the busbars, and effectively avoiding the problem of poor contact caused by using the busbars for series connection.

Resumen de: EP4672342A1
A foldable solar panel includes a power generation layer (100) and two adhesive film layers (200) located on two opposite sides of the power generation layer (100). The power generation layer (100) includes a plurality of sub-power generation panels (110) arranged at intervals and an interconnection wire (120). A bent region (2000) is formed in a gap between two adjacent sub-power generation panels (110). The two adjacent sub-power generation panels (110) are electrically connected by the interconnect wire (120) passing through the bent region (2000). An isolation layer (300) is arranged between the interconnect wire (120) and the adhesive film layer (200).
