Have you heard of the nano cone? A new type of nano-material, nano-cone has another high-efficiency light absorption capability due to its special vertebral structure, which is another innovation in the development of solar cells.
Scientists from the Royal Melbourne Institute of Technology have recently developed a nanomaterial called the nanocone. This nanomaterial can be applied to solar photovoltaic panels because it enhances the efficiency of solar cells by enhancing the ability of solar panels to absorb light. Their research results are published in the journal Science Advances, which details the working principle of nano-cones and nano-cones, and hopes that this nano-material can be widely used in the field of solar photovoltaic panels.
The superior performance of nano-cone materials is mainly due to its extremely high refractive index—the inner material of each vertebral body is an insulator and the outer material is a conductor—seen under the microscope, the nano-cone material is arranged like many bullets stand up. Nano-cones have the same mechanism as other topological insulators, causing changes in electron concentration when photons hit the material, causing vibration. Each vertebral body is composed of a metal-coated outer shell and a dielectric core. This structure can greatly enhance the material's ability to absorb light, making the nano-cone not only applicable to solar cells, but also to solar photovoltaic panels. , optical fibers, waveguides and lenses. Researchers add that if a nano-cone is applied to a solar thin-film cell, it will increase the absorbance by 15% in the visible and ultraviolet range.
Researchers point out that this is the first time they have prepared this nanostructured material, and more importantly, no new process technology is required to prepare this material. And because of the enhanced light absorption capacity of this new material, both current and photoelectric conversion efficiency will be improved.
Unlike other nanomaterials, the nano-cone is shock-insensitive to polarization. This also means that the nano-cone does not need to be vertically aligned along the nano-crack and can be directly integrated into the current hardware. Cones have broad application prospects. And the researchers pointed out that their next research direction is to explore different types and shapes of plasma.
