Solar cell efficiency is expected to increase by 50%

Researchers at the University of California, Santa Barbara, have demonstrated that by adding a small molecular organic solar cell between the active layer and the electrode to tune the thickness of the active layer and embedding a zinc oxide optical spacer, small organic organic solar cells can be The efficiency gains a 50% increase from the current 6.02% to 8.94%.

The researchers explained in the paper that small molecule organic solar cells have several advantages over organic polymer solar cells: relatively simple synthesis, high charge carrier mobility, same-sized particles, and better Reproducibility, etc. (â–¡Kristin)

Steel Mills Roller Bearing

Rolling Mill Bearing for blanking machine .
Rolling mill bearings are the bearings used on the roll necks and rollers of metallurgical, mining and other rolling mill stands. Cylindrical roller bearings are often used to withstand radial loads, deep groove ball bearings or angular contact ball bearings, or radial design or thrust design Tapered Roller Bearings to withstand axial loads. Most of them are lubricated and cooled by means of oil-air lubrication or oil mist lubrication.
Rolling Mill Main Application:
Cold rolling mill, Hot rolling mill, Blanking machine

Roll neck and drum for metallurgy, mining and other rolling mill stands
