Photovoltaic module

A photovoltaic module, comprising:

• at least two photovoltaic cells, each of the photovoltaic cells comprising:
• a photovoltaic device, the photovoltaic device having a light-receiving surface and a back surface opposite the light-receiving surface;
• a surface electrode disposed on the light-receiving surface of the photovoltaic device, the surface electrode comprising:
• at least one bus electrode, the bus electrode comprising:
• at least two line electrodes disposed on the light-receiving surface;
• and
• a plurality of finger electrodes disposed on the light-receiving surface and extending in a direction different from a lengthwise direction of the bus electrode, wherein the finger electrodes intersect and are electrically connected with the line electrodes, each of the finger electrodes is disposed partially out of a region where the bus electrode is disposed, and any adjacent two of the line electrodes and any adjacent two of the finger electrodes define an electrodeless space in the region where the bus electrode is disposed;
• and
• a back electrode disposed on the back surface of the photovoltaic device;
• and
• at least one ribbon electrically connecting the photovoltaic cells, wherein the ribbon is partially disposed on the light-receiving surface of the photovoltaic device of one of the photovoltaic cells and covers the line electrodes of the bus electrode.
