no. 1 approach
[0102] Next, a first embodiment of a solar cell and a method of manufacturing a solar cell according to the present invention will be described with reference to the drawings.
[0103] In addition, in each drawing in the following description, the ratio of each member is appropriately changed in order to make each member recognizable in size.
[0104] (Solar battery)
[0105] figure 1 is a cross-sectional view showing an amorphous silicon solar cell.
[0106] like figure 1 As shown, the solar cell 10 is a so-called monolithic solar cell, and has a structure in which a photoelectric converter 12 is formed on one surface 11 a (first surface, hereinafter referred to as the rear surface 11 a ) of a transparent insulating substrate 11 . In addition, a texture layer 17 to be described later is arranged between the back surface 11 a and the photoelectric converter 12 .
[0107] The substrate 11 is formed of, for example, an insulating material having excellent sunlight transmitta...
no. 2 approach
[0184] Next, a second embodiment of the solar cell and the solar cell manufacturing method of the present invention will be described based on the drawings.
[0185] In the second embodiment, configurations or methods that are different from those in the first embodiment described above will be described, and components that are the same as those in the first embodiment will be given the same symbols, and descriptions thereof will be omitted or simplified.
[0186] The difference between the second embodiment and the first embodiment lies in the method of forming the texture layer 17 . Specifically, in the second embodiment, the texture layer 17 is formed using an inkjet device.
[0187] (inkjet device)
[0188] First, refer to Figure 4A and Figure 4B , the structure of the inkjet device will be described.
[0189] Figure 4A It is a cross-sectional view showing an inkjet device used in the texture layer forming step according to the second embodiment of the present inv...
no. 3 approach
[0221] Next, a third embodiment of the solar cell and the solar cell manufacturing method of the present invention will be described based on the drawings.
[0222] In the third embodiment, configurations or methods that are different from those of the first and second embodiments described above will be described, and components that are the same as those in the first and second embodiments will be given the same symbols, and descriptions thereof will be omitted or simplified.
[0223] The third embodiment differs from the first and second embodiments described above in the method of forming the texture layer 17 . Specifically, in the third embodiment, the texture layer 17 is formed using a spray method. Hereinafter, the method of forming the texture layer 17 using a sprayer is called a spray method.
[0224] First, refer to Figure 7A and Figure 7B , and the spray method will be described.
[0225] Figure 7A It is a side view for explaining the process of forming a te...
