Problems solved by technology
Therefore, the shadowed thin film photoelectric conversion unit will have extremely high impedance, resulting in a significant drop in the overall module output
Furthermore, the current cannot flow evenly in the thin film photoelectric conversion unit, and it is easy to cause the so-called hot spot phenomenon

Embodiment Construction
[0043] Please also refer to Figure 1A and Figure 1B . Figure 1A It is a top view of the thin film photoelectric conversion module 1 in an embodiment of the present invention, and Figure 1B for Figure 1A The side cross-sectional view of the thin film photoelectric conversion module 1 along the H1 direction.
[0044] The thin film photoelectric conversion module 1 sequentially includes a substrate 16 , a first electrode layer 10 , a photoelectric conversion layer 12 and a second electrode layer 14 . The first electrode layer 10 includes a plurality of first electrode rows 100 and an electrical resistive material 102 . In one embodiment, the first electrode layer 10 is a front electrode. The first electrode arrays 100 are substantially parallel to each other and extend along the direction of current flow, that is, along Figure 1A Extend in the horizontal direction 11. The direction of current flow is the direction in which current flows in the thin film photoelectric con...

A thin film photoelectric conversion module is provided. The thin film photoelectric conversion module includes a substrate and a plurality of photoelectric conversion cells formed on the substrate and connected to each other in series to form a series-connected array. The thin film photoelectric conversion module further comprises a plurality of first electrode rows extending along a current flow direction and a resistive material electrically connected to adjacent two of the first electrode rows, wherein the resistive material has an electrical resistivity no less than 10-9 ohm-cm, wherein when the resistive material is a material different from that of the first electrode rows, the resistive material makes adjacent two of the first electrode rows at least partially connected, and when the resistive material is a material the same as that of the first electrode rows, the resistive material makes adjacent two of the first electrode rows partially connected.
Description
technical field [0001] The invention relates to a photoelectric conversion device, and in particular to a thin film photoelectric conversion module and a manufacturing method thereof. Background technique [0002] A solar cell is a device that converts the energy of sunlight into electricity through the photoelectric effect. Generally, such a thin film photoelectric conversion module includes a plurality of thin film photoelectric conversion units connected in series to perform photoelectric conversion. [0003] When stains such as leaves or bird droppings adhere to the light-receiving surface of the thin film photoelectric conversion module, the corresponding thin film photoelectric conversion unit will be partially or completely covered, thereby reducing the photoelectromotive force. The reduced photoelectromotive force will make the thin film photoelectric conversion unit become a reverse series diode on the energy generation path. Therefore, the shaded thin film photoe...
