According to the Russian "STRF" science website on March 25, the research group of the Institute of Physics and Technology of the Russian Academy of Sciences to develop a new solar thin film battery, this silicon-based solar cell module, the photoelectric conversion efficiency theory Up to 27%. Russia's "Хевел" company, through its cooperation with Switzerland, produces solar cells at the Russian plant to produce thin film solar modules with an annual output of 100 megawatts. Production technology in Switzerland ensures that the solar cell modules produced have a photoelectric conversion efficiency of 8.9%. In order to improve the technology and further improve the photoelectric conversion rate, in 2010, Russia "Хевел" company established a thin film solar cell technology research center at JOMEX Institute of Physical Technology. The researchers of this center gradually changed the photoelectric conversion of the thin film solar cell Efficiency is increased to 10% and further to 12%. In a parallel study, Russian researchers are working to perfect a new product based on thin-film silicon solar cells. In 2012, Japan's Sanyo solar cell patent based on crystalline amorphous heterojunction technology expires, the Russian scientists with the patented technology, the use of the Russian Nobel Prize winner Alferov on photoelectric heterogeneity research results, research and development A new solar thin film battery. The new solar thin film battery based on silicon materials, the production of the use of plasma chemical deposition method to form a layer of amorphous silicon nanocrystalline thin film on the surface of the crystalline silicon. At present, the photoelectric conversion rate of industrial samples produced by the research center based on the thin film solar module of this technology has reached 21%, which is nearly twice that of the traditional thin film solar module. Titanium Dioxide(TIO2)
Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.

The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
