    摘要: An electroplating solution to electroplate a selenium containing film on a conductive surface is provided. The electroplating solution includes a solvent, a selenium source material that dissolves in the solvent; an anti-coagulation agent that inhibits Se particle growth and promotes Se particle dispersal. The pH value of the electroplating solution is in the range of 2-10.

    摘要: The present invention relates to gallium (Ga) electroplating methods and chemistries to deposit uniform, defect free and smooth Ga films with high plating efficiency and repeatability. Such layers may be used in fabrication of electronic devices such as thin film solar cells. In one embodiment, the present invention provides a solution for application on a conductor that includes a Ga salt, a complexing agent, a solvent, and a Ga-film having submicron thickness is facilitated upon electrodeposition of the solution on the conductor. The solution may further include one or both of a Cu salt and an In salt.
