He was led by professors Jiang Tang and Ted Sargent of the University of Toronto in Canada. The international scientific team, including the King Abdullah University of Science and Technology of Saudi Arabia and the researcher of Pennsylvania State University, used inorganic ligands instead of organic molecules to encapsulate quantum dots. By making the surface passivated (not easily chemically reacting with other substances), a colloidal quantum dot (CQD) solar cell having the highest conversion efficiency (up to 6%) has been developed to date. This study was published in the recent issue of Nature Materials.
Light-absorbing nanoparticle quantum dots are nanoscale semiconductors that capture light and convert it into energy, and can be used to make solar cells that are cheaper and more durable than silicon-based solar cells. To solve the problem of closer integration of quantum dots and improved conversion efficiency, scholars have used the ligands of sub-nanometer atoms to wrap a single layer of atoms around each quantum dot, making the quantum dots a very tight solid to save space. , and remove charge traps through tight packaging - where electrons fall into place.
Quantum dots are tightly packed together and eliminate charge traps, allowing the electrons to pass through the solar cell quickly and smoothly. The laboratory assigned by the National Renewable Energy Laboratory confirmed that the newly developed colloidal quantum dot solar cell not only reached the highest current, but also achieved a record of overall energy conversion efficiency of 6%. The University of Toronto has signed a technology licensing agreement with the King Abdullah University of Science and Technology in Saudi Arabia to promote the global commercialization of this technology.
1X37 Stainless Steel Wire Rope
There are two types of wire rope corrosion: external corrosion and internal corrosion.
Inspection of external corrosion: Visually inspect the wire rope for rust, pitting, and loose wire.
Internal corrosion is not easy to detect. Corrosion of wire rope is the killer of 1*37 Stainless Steel Wire Rope, so it is very important to prevent the occurrence of wire rope corrosion. If it is a wire rope with a smaller diameter (≤20mm), the wire rope can be bent by hand for inspection; if the diameter is larger, the wire rope can be inserted into the fiber for internal inspection. After the inspection, the wire rope should be restored to its original state, taking care not to damage the rope core , and add lubricating grease.
The materials of 1*37 steel wire rope are 201, 304, 316, 310, galvanized and so on. Specifications are generally 0.3-8mm
