Abstract: Described herein is an etching solution and the method of using the etching solution comprising water, phosphoric acid solution (aqueous), an organosilicon compound as disclosed herein, and a hydroxyl group-containing water-miscible solvent. Such compositions are useful for the selective removal of silicon nitride over silicon oxide.

Abstract: A module structure includes a front sheet, a back sheet opposite to the front sheet, and a solar cell disposed between the front sheet and the back sheet. A first encapsulation film is disposed between the solar cell and the front sheet, and a second encapsulation film is disposed between the solar cell and the back sheet. The first encapsulation film and the second encapsulation film include an encapsulation material, which includes a resin and a fluorescent molecule. The fluorescent molecule includes a fluorescent group bonded to a polyhedral oligomeric silsesquioxane.

Abstract: A solar photovoltaic module including a solar cell, a first package layer and a second package layer is provided. The solar cell has a first surface and a second surface opposite to the first surface. The first package layer is formed on the first surface. The second package layer is formed on the second surface. The first package layer and the second package layer are made of different crosslinked materials, and a difference between the crosslink density of the first package layer and the crosslink density of the second package layer is equal to or less than 15%.

Abstract: A module structure is provided, which includes a front sheet, a back sheet opposite the front sheet, and a solar cell disposed between the front sheet and the back sheet. A first encapsulate film is disposed between the solar cell and the front sheet, and a second encapsulate film disposed between the solar cell and the back sheet. One or both of the front sheet and the second sheet includes a support layer and a light conversion layer on the support layer, wherein the light conversion layer includes a fluorescent molecule and hydrogenated styrene elastomer resin. The light conversion layer is disposed between the support layer and the solar cell.

Abstract: The rowing exercise apparatus includes a frame structure on which is mounted at one end a seat for supporting a user in seated position. A pedal mechanism for positioning the feet of the user thereon is provided at the foot end of the frame. On each longitudinal side of the frame, there is provided a scully-type or rowing mechanism. Each rowing mechanism typically includes (a) a pivotally mounted swing rod assembly including a swing rod, (b) a swinging mechanism including a cylinder and piston rod assembly, (c) a compound connector for regulating the swinging mechanism, and (d) a respective swinging arm carrying a movable handle. The swinging arm is connectable to the connector in such a way so as to allow adjustment of the swinging action of the swinging arm.

Abstract: A folding exercise bike including a transmission box driven by pedals making a rotating bush at its output shaft drive a universal joint and drive a saddle supporter, thus permitting forward and backward motion of the saddle. Meanwhile, the universal joint drives connecting rods to pull a handle to turn the handle inward and outward, thus making the bike have a multi-functional exercise effect. The main frame, handle supporter and saddle supporter are also capable of being knocked down to reduce the volume of the bike for easy packing, transport and warehousing.
