To be able to form a copper-zinc-tin alloy which optionally comprises at least one chalcogenide and thus forms a semiconductor without the use of toxic substances a metal plating composition for the deposition of a copper-zinc-tin alloy is disclosed, wherein said metal plating composition comprises at least one copper plating species, at least one zinc plating species, at least one tin plating species and at least one complexing agent and further, if the alloy contains at least one chalcogen, at least one chalcogen plating species. The metal plating composition additionally comprises at least one additive, selected from the group comprising disubstituted benzene compounds having general chemical formula I, wherein R1 and R2 are the same or different, are selected independently from the group comprising OH, SH, NR3R4, CO-R5, COOR5, CONR3R4, COSR5, SO2OR5, SO2R5, SO2NR3R4 and the salts thereof or have the aforementioned meanings and form a common condensation chain; with R3 and R4 being the same or different, being selected independently from the group comprising H and alkyl; and with R5 being selected from the group comprising H, alkyl and hydroxyalkyl. Such alloys comprising at least one of sulfur and selenium may be used as an absorber in a thin film solar cell, which comprises a substrate (a) being coated with a back contact (b), the absorber layer (c), a buffer layer (d), a TCO / window layer (e) and a front grid (f).
摘要:
A plating method of a negative electrode can of a flat alkaline cell and a plating apparatus thereof are provided, by which a plated-coating layer can be formed only in a concave of the negative electrode can, a plating liquid is not uselessly consumed, and an inner face of the negative-electrode-can can be washed with a small amount of washing liquid. An electroless plating liquid is filled into the concave of the negative electrode can so as to form a plated-coating layer on an inner face of the concave. The electroless plating liquid is recovered from the concave of the negative electrode can, then a washing liquid is filled into the concave to wash the inner face of the concave. Then, the washing liquid is recovered from the concave of the negative electrode can, and then air is filled into the concave to dry the inner face of the concave.
