Effect of Infrared Radiation on the Hydrogen in Thin Films Double Barriers Based Melt Silicone-Germany

Image
Abstract Possibilities of plasma chemical deposition of α-Si 1-x Ge x :H (x=0÷1) films undoped and doped with PH 3 or B 2 H 6 have been analyzed from the viewpoint of their application in p-i-n structures of solar cell. The optical properties are considered, and the amount of hydrogen contained in those films is determined. The film properties are found to strongly depend on the film composition and the hydrogenation level. The number of hydrogen atoms in the films is varied by changing the gas mixture composition, and IR absorption in α-Si:H and α-G e :H films is measured. The α-Si:H and а-Si 0,88 Ge 1,2 :H films were used to fabricate three-layer solar with an element area of 1,3 sm 2 and an efficiency (η) of 9.5 %.

The non-stoichiometric tungsten oxide nanostructure, WO2.9 (W25O73, dark blue color) is an efficient electrocatalyst for hydrogen evolution in acidic water, which has shown promise as an alternative to platinum (Nature Communications 2015, 6, 8064(1-7)). Generally speaking, the oxygen vacancies or oxygen deficiencies can affect the electronic band structure and enhance the conductivity. Blue tungsten oxide-based materials, WO2.8 (W5O14) are used as promising anode materials for lithium-ion batteries (Adv. Funct. Mater. 2018, 28, 1707500). And sea urchin-like WO2.7 (W18O49, purple color) nanowire can be used as a substrate material to magnify the substrate-analyte molecule interaction, leading to significant SERS response, even comparable to noble metals without ‘hot spots’. The extremely high electrocatalytic activity and SERS response can probably be attributed to the presence of oxygen deficiencies, either intrinsic or on the surface (Nature Communications 2015, 6, 7800(1-7)).

The Erroneous Banishment of Plastics Authorized by Walter Eevers Since some months, youth is marching in the streets of several cities throughout Europe. They scream for political attention for the fight against climate change. The debates in the press and on social media go into all directions and give attention to technological solutions to fight climate change, the need for personal lifestyle adaptation but also to fights against nuclear power generation, air traffic etc. But in the margin of these protests also plastics and the use of plastics are condemned in many of these communications.
