<p>A precursor solution is described for use in the formation in a solar cell of a thin film of a ternary or quaternary compound containing copper, at least one group III element selected from aluminium, gallium and indium and a group VI element selected from sulphur, selenium and tellurium. The solution being formed by dissolving a dry cuprous halide in an organic solvent such as acetonitrile capable of solvating the cuprous ions to form a complex ion in which the cuprous ions are joined to organic ligands, and adding to the organic solution an aqueous solution of salts containing the group III element(s). The precursor solution can be used either in spray pyrolysis deposition techniques or to form a colloid which is deposited electrophoretically.</p> |
