Embodiment approach 1-2
[0152] figure 2 is a schematic cross-sectional view showing the layer structure of main components of a solar cell module (Embodiment 1-2) obtained by electrically connecting a plurality of solar cells of the present invention (Embodiment 1-1) in series.
[0153] This solar cell module can be manufactured as follows.
[0154] First, the first conductive layer formed on the substrate 1 is patterned at prescribed intervals by a laser scribing method to form a plurality of scribe lines in which the conductive layer is removed. Accordingly, a plurality of first conductive layers 2 electrically isolated from each other are formed, and a solar cell formation region is provided on each first conductive layer 2 .
[0155] Among the plurality of first conductive layers 2, the first conductive layer 2 at one end in the direction perpendicular to the scribe line 10 is formed to have a smaller width, and no solar cell is formed on the first conductive layer 2 with the smaller width. on...
