According to foreign media reports, researchers from the Institute of Solar Energy and Hydrogen Research (ZSW) in Karlsruhe Institute of Technology (KIT) and Baden-Württemberg in Germany recently published papers in the magazine “Advanced Optical Materialsâ€, claiming that they imitation rose petals The texture produces a thin film that can significantly increase the energy conversion efficiency of the solar cell. KIT pointed out in a report: “Scientists have discovered through electron microscopy that the surface of the rose petals is composed of densely arranged microscopic structures, which allow it to absorb more light.
The researchers used silicon-based polymers to make molds with the same structure as rose petals, and then poured transparent optical glue. After the glue was cured, they obtained a transparent film with the same structure as the rose petals.
The researchers placed the fabricated film on the surface of the solar cell and found that it increased the energy conversion efficiency of solar cells by 12%.
