DONGHWAN, Kim; MCCANDLESS, B.E; HEGEDUS, S.S  e  BIRKMIRE, R.W. Cu_xS back contact for CdTe solar cells. Rev. mex. fis. [online]. 2007, vol.53, suppl.1, pp.5-8. ISSN 0035-001X.

Copper sulfide (Cu_xS) films were studied as a back contact material for CdTe solar cells. The Cu_xS films were made by chemical bath deposition in aqueous solution. Annealing at 200°C in Ar improved the performance of the solar cells. Using the CdS/CdTe/Cu_xS/C structure, an open-circuit voltage (V_oc) higher than 840 mV and an energy conversion efficiency higher than 11% were obtained.

Palavras-chave : Copper sulfide; cadmium telluride; solar cells; contact resistance.
