This utility model belongs to the field of electroplating technology and discloses a steel strip for clamping packaged chip strips. The lower end of the steel strip body is provided with multiple conductive supports, each corresponding to an elastic clip. The upper end of the elastic clip is connected to the steel strip body above the conductive support, and the lower end of the elastic clip is the clamping end that cooperates with the conductive support to clamp the packaged chip strip. The clamping end of the elastic clip is provided with a first insulator molded into shape, and a second insulator is molded onto the conductive support. A conductive contact point is provided on one side of the bottom of the conductive support. The conductive contact point cooperates with the lower end of the first insulator to clamp the packaged chip strip. When the conductive contact point abuts against the lower end of the first insulator, the lower end of the first insulator covers the conductive contact point. This utility model minimizes the tin plating of the conductive supports and elastic clips, reducing energy loss during electroplating and minimizing the need for deplating after material handling.

This invention discloses a PECVD equipment and a silicon wafer passivation method. The PECVD equipment includes a reaction chamber and an RF power supply. The reaction chamber includes a base, an electrode plate vertically disposed within the reaction chamber, and a wafer cassette. The wafer cassette is used to hold multiple stacked silicon wafers and is positioned at a predetermined location on the base, such that the wafer cassette, after entering the reaction chamber, can be arranged on both sides of the electrode plate. The wafer cassette has an opening so that the passivation-to-be-treated sides of the stacked silicon wafers face the electrode plate. The RF power supply is electrically connected to the electrode plate. The wafer cassette and the base are grounded. The reactive gas introduced into the reaction chamber dissociates to form plasma, which is then deposited on the passivation-to-be-treated sides of the silicon wafers adjacent to the electrode plate. This invention avoids the need for plating around the wafer, shortens process time, reduces process temperature, improves equipment efficiency, and reduces breakage rate.

The invention provides a laminated photovoltaic device and a production method, and relates to the technical field of photovoltaics. The laminated photovoltaic device comprises an upper-layer battery unit, a lower-layer battery unit, an insulating layer and a middle series structure, the upper-layer cell unit is a thin film solar cell; the lower-layer battery unit is provided with a light-facing surface and a backlight surface which are oppositely arranged, and a side surface connected with the light-facing surface and the backlight surface; and the insulating layer at least wraps the side surface of the lower-layer battery unit. The insulating layer is wrapped on the side surface of the lower-layer battery unit, so that the coating or winding plating of the thin film solar cell on the lower side surface of the thin film solar cell is positioned on the insulating layer and is not in contact with the side surface of the lower-layer battery unit, and the direct coating or winding plating of the thin film solar cell on the side surface of the lower-layer battery unit is avoided; the short circuit of the upper and lower layers of battery units is reduced to a great extent, and the power generation efficiency and the production yield of the laminated photovoltaic device can be improved. The production process is simple, and the production cost is low.
