The invention discloses a thin-film double-glass photovoltaic module which comprises cover plate glass and back plate glass, a back electrode layer, an absorption layer, a buffer layer and a front electrode layer are sequentially stacked between the cover plate glass and the back plate glass, the absorption layer, the buffer layer and the front electrode layer form an absorption front electrode layer, and a group of first laser scribing lines are arranged on the back electrode layer at intervals. A group of second laser scribing lines are arranged on the absorption front electrode layer at intervals; the absorption front electrode layer between each pair of second laser scribing lines and the first laser scribing line is provided with vertical through holes, a group of wires correspondingto the through holes are laid on the top surface of the front electrode layer, and one end of each wire penetrates through the corresponding through holes to be connected with the back electrode layer, so that sub-cells are c
