The purpose of the present invention is to provide an interconnector for solar cells, which reduces the stress acting on a solar cell and suppresses warping and cracking of the solar cell. An interconnector for solar cells of the present invention is characterized by comprising an electrically conductive wire part and a surface layer that is formed on at least one wide surface of the electrically conductive wire part. The interconnector for solar cells is also characterized in that the surface layer has a function of reducing the stress that is caused by the difference between the thermal expansion coefficient of the electrically conductive part and the thermal expansion coefficient of a solar cell, said stress being generated when the interconnector is joined to the solar cell.

There is disclosed is a method comprising surface-processing a Sn based, Sn alloy based or Sn-Zn alloy based solder particle (1), applied as a coating, such as by electrical plating or melt plating, to the surface of a metal material, such as iron, a steel plate or copper, with a phosphate and a silicium containing compound, to form a protective film (2). There are also disclosed a solder material (6) in which a protective film (2) formed of a phosphate and a silicium containing compound is formed on the surface of the Sn-Zn based solder particle (1), and a solder paste formed of this solder material (6) and the flux.

A Pb-free hot-dipped Sn-Zn plating provided steel plate or sheet having excellent corrosion resistance and workability, which is especially suitable as a material for automobile fuel tanks. In particular, a hot-dipped Sn-Zn plating provided steel plate or sheet, comprising a steel plate or sheet having, formed on its surface, a hot-dipped plating layer comprising 1 to 8.8 mass% of Zn and the balance composed of 91.2 to 99.0 mass% of Sn and unavoidable impurities and/or incidental components, wherein the plating layer comprises Sn dendrites having arms whose interspace is filled with Sn-Zn binary eutectic tissue, and wherein the area ratio of Sn dendrites in the plating layer is in the range of 5 to 90% while the arm spacing of Sn dendrites is 0.1 mm or less. Preferably, a hot-dipped Sn-Zn plating provided steel plate or sheet excelling in corrosion resistance and workability, comprising a steel plate or sheet having, formed on its surface, a discontinuous FeSn2 alloy phase whose area ratio is in the range of 1 to less than 10%, the discontinuous FeSn2 alloy phase overlaid with a layer whose composition is Sn-(1 to 30 mass%)Zn. Still preferably, the surface roughness in terms of RMS of the discontinuous FeSn2 alloy phase is in the range of 0.1 to 2.5 mum.
摘要:
Für ein Zinn(Sn)-Bad zum Verzinnen von Stützkörpern von Gleitlagem wird vorgesehen, dem Sn-Bad zumindest einen Legierungsbestandteil zuzugeben, der bei Betriebstemperatur des Bades eine höhere Affinität zu Eisen(Fe) als Sn aufweist. Der Legierungsbestandteil wird bis zu seiner Löslichkeitsgrenze in der Sn-Schmelze gelöst. Durch Zugabe solcher Legierungsbestandteile werden auf dem Stützkörper Zwischenschichten zwischen Stützkörperoberfläche und Gleitlagermetall gebildet, die zu einer ausreichenden Bindungsfestigkeit des Gleitlagermetalls auf dem Stützkörper führen. Ein Oxidieren der Fe-Oberfläche der Stützkörper wird weitgehend unterbunden. Bevorzugt wird dem Sn-Bad Zink(Zn) zugegeben. Ein Schliffbild eines nach dem Verfahren hergestellten Stützkörpers mit einer Sn-Zwischenschicht, die zumindest einen Legierungsbestandteil aufweist, der eine höhere Affinität zu Fe als Sn aufweist, zeigt Figur 2. Die Zwischenschicht wurde auf dem Stützkörper durch Eintauchen in ein Sn/Zn-Bad mit 50 Gew% Sn und 50 Gew% Zn (Schmelzbadtemperatur 350°C) aufgebracht.
摘要:
A joining structure for metal members, which joins a first metal member and a second metal member together by soldering, wherein at least one of the first and second metal members are SnZn-alloy-plated, and an SnAg alloy is used as a solder, whereby the heat deterioration of a solder and plating-to-plating contact corrosion can be prevented, a soldering spreading is improved, and the corrosion resistance and qualities such as a joint strength of a joining structure are also improved.
