Double-layer reflection-decreasing film for silicon solar cell and preparation method thereof

The invention relates to a double-layer antireflecting film of a silicon solar cell and a preparation method thereof. A layer of a silicon nitride film (2.1) is deposited on the positive surface of a silicon chip underlayer (1); and a layer of a silicon dioxide film (2.2) is deposited on the silicon nitride film (2.1) to form a silicon nitride/silicon dioxide double-layer reflecting film (2). The method comprises: step one, SiH4 and NH4 react on the silicon chip underlayer manufactured with wool to deposit a layer of the silicon nitride film through a plasma enhanced chemical vapor deposition method; and step two, SiH4 and N2O react on the silicon nitride film to deposit a layer of the silicon dioxide film through the plasma enhanced chemical vapor deposition method. Compared with the prior monolayer antireflecting film, the double-layer antireflecting film has smaller refractive index and improves the cell efficiency. The method can be completed in the same equipment and simplifies the ...

Combination cup and brewer

A system produces a brew from an infusible brew substance using a combination of a mug and a brewer housed within the mug. The mug includes a vessel inside the mug that holds the water used to brew the brew. The vessel has an exit port below its upper rim. A removable stopper closes the vessel. A siphon tube fits through the exit port and extends downward within the vessel to the siphon's suction end. A heating element is immersed in water within the vessel. When electrically energized, the heating element vaporizes the water, which rises to the top and pushes the water downward into the suction end. A mesh filter holds the infusible brew substance or the substance is placed in the bottom of the mug. The mesh filter is located below the siphon sticking out of the exit port. Water flows through the filter into the mug outside the vessel.
