title = "Challenging the Electrodeposition of Multinary Semiconductor Compounds: Case of CuInSe",
abstract = "The electrodeposition of multinary compounds is of key importance for future technologies. Cu-In-Se system represents a case example, with a great potential in the field of photovoltaics. At IRDEP we achieved efficiencies up to 11.5\% based on electrodeposited Cu-In-Se material. In the present paper, nucleation and growth steps of CuInSe2 are studied by polarization, impedance spectroscopy and SEM. The bulk composition is measured by x-ray fluorescence. The chemical environment of Cu, Se and In and the surface composition are analysed by XPS. A quasi-instantaneous 3D nucleation is observed. Binary Cu-Se nuclei are first obtained, which induce the incorporation of indium leading to CuInSe2. With increasing growth, secondary phases and Se(0) are obtained. At the threshold of potential corresponding to indium incorporation, a blocking adsorbate is formed, which is reduced at higher cathodic overvoltage into Cu-In-Se compound. These results are discussed in terms of general behavior of multinary compound deposition.",
