Researchers at Rice University in the United States have found a way to simplify the manufacturing of solar cells by using the top electrode as a catalyst to turn pure silicon into more valuable "black silicon." Black silicon has a highly textured surface with nanoscale protrusions or pores that are smaller than the wavelength of light, allowing it to efficiently collect light from any angle at any time of the day. Andrew Barron, professor of chemistry at Rice University, said that he and the...

Solar cells convert 3/4 of the solar spectrum into electrical energy, where the infrared spectrum is completely lost in standard solar cells. In contrast, black silicon solar cells are specifically designed to absorb this portion of the spectrum, and researchers have recently succeeded in doubling their overall efficiency. Solar energy shines from a deep blue sky, and then rooftop solar cells convert solar energy into electricity. However, not all light is converted to electrical energy, and...
Carbon dioxide can also be turned into automotive fuel Carbon dioxide fuel conversion Recently, a group of researchers from the University of California, Los Angeles conducted a very meaningful experiment. With the help of genetically engineered microorganisms, they converted carbon dioxide into isobutanol and isopentane that can be used as fuel for automobiles and internal combustion engines. Alcohols make carbon dioxide incredible "reverse burning" and "closed circulation". As a result, we...
First, amorphous silicon: ● Photovoltaic cells (sheets), including monocrystalline silicon, polysilicon, amorphous silicon, and thin film batteries. Monocrystalline and polycrystalline batteries are the most used, and amorphous batteries are used for small systems and calculators for auxiliary power. ● Amorphous silicon is a direct-energy semiconductor with many so-called “dangling bonds” inside its structure, that is, electrons that do not have bonds with the surrounding silicon atoms. These...

After China officially proposed the specific target of carbon reduction in 2020, efforts to promote energy-saving and emission-reduction technologies, use low-carbon or non-carbon fuels, and promote carbon trading have received unprecedented attention. The reporter interviewed related experts in this regard. They proposed that while emphasizing the source control of CO2 emissions, they should not neglect the value of CO2 resource utilization. Wang Xianhong, a researcher at the Changchun...
Since the beginning of this year, the titanium dioxide industry in China has continued its upward trend last year, and companies generally maintain a high level of profitability. However, a good market situation can hardly conceal the hidden dangers of overcapacity and product homogeneity. At present, the export of titanium dioxide is restricted by the state's cancellation of export tax rebates for "two high and one capital" products, and international giants such as DuPont and Coscom are...
