Abstract :
This work shows results for CdS/CdTe photovoltaic cells grown in a homemade in-line close-spaced sublimation equipment. In this system, most of the steps of cell fabrication were carried out continuously, using dry processing, without breaking vacuum. The efficiency values ranged from 3.5 to 7%. These cells were compared with unfinished devices prepared in the in-line system and finished (heat treatment and contact processing) at NREL. The results suggested that some steps in the cell fabrication should be optimized.
