The fabrication of CdTe/CdS solar cells is described using close-spaced sublimation (CSS) CdTe films deposited at lower temperatures (below 500 °C). The potential of this process and the influence of several parameters, such as the temperature and type of CdCl2 treatment and etching process, are studied. Using a lower temperature in the production of the CdTe films avoids the diffusion of impurities, from the soda-lime glass substrate. The limiting factors for the efficiency of the cells prepared by the vapor process, as the treatment temperature increases, is the diffusion of sulfur into the CdTe film, with the consequent thinning of the CdS layer, and the deterioration of the front contact.
