[0023] Please refer to Figure 1A and Figure 1B as shown, Figure 1A and Figure 1B They are a combined schematic diagram and a cross-sectional view of a solar cell device 2 according to the first embodiment of the present invention, respectively.
[0024] The solar cell device 2 includes a substrate 21 , at least one solar cell unit 22 and at least one line-condensing lens unit (hereinafter referred to as the lens unit) 23 . In this embodiment, a solar cell unit 22 and a lens unit 23 are disposed on the substrate 21 as an example for illustration.
[0025] The solar cell unit 22 is disposed on the substrate 21 . The material of the substrate 21 may include, for example, plastic or glass, which is not limited here. The material of the solar battery unit 22 may, for example, include monocrystalline silicon, polycrystalline silicon, microcrystalline silicon, amorphous silicon or III-V materials, and is not limited here.
[0026] The solar battery unit 22 has a long side 221...
