Since the battery is made of plastic as the main material, the cost is much lower than that of a conventional solar cell using polycrystalline silicon as a material. Li Guangxi said that unlike solar cells that used to absorb only visible light in sunlight, this battery can absorb near-infrared light in addition to visible light, because it uses a stack of two solar cells that overlap.
