The world is on the brink of catastrophe and renewable energy sources are not available as quickly as possible. Probably the biggest source of unused new energy is the Sun. It’s amazing how much new energy research has to say about the power of the sun.

A new paper published in The European Physical Journal D observe that changes in the porous nature of the silk reduce the reflection slightly and are therefore more suitable for solar protection technology. The paper was written by Daohan Ge, Zhou Hu, Zhiwei Fang, Chao Ni, and Liqiang Zhang of the Institute of Intelligent Flexible Mechatronics, Jiangsu University, China, and Shining Zhu of the National Laboratory of Solid State Microstructures, Nanjing University , China.

In the paper, the authors pointed out that porous silicon can be used as a form of fine -grained film, which can effectively reduce optical sensitivity and improve the efficiency of the optical application of its applications. manufacturer that specializes in electrochemical etching method for the preparation of porous silicon for. of its efficiency and inexpensive nature.

Currently, the reflectivity of porous silicon prepared using electrochemical methods is about 5 to 10 percent, with a low light intensity of 4.7 percent for light in the wavelength of 300 to 1000 nanometers. .

Other studies have explored the lightweight properties of this silk, but the difference in this study is that the compound has applied this material to the porous nature of the silicon.

Therefore, the team used the FDTD method to calculate and compare the surface roughness of porous silicon structures with different pore sizes.

What the researchers said was that they found that the porous silicon system when prepared under the best corrosion conditions could have an average reflectivity as low as that. 2.3 percent for illumination at an event wavelength of 300 to 1000 nm.

They found that a pore size of 300 to 700 nm can achieve low -density silicon, incorporating these guidelines in the way for the design and preparation of low -density silicon silicon structures. coming.
