CdTe Solar Cells at CEA / LETI

The present communication will present the results obtained at CEA/LETI in Grenoble, France, in the frame of an experimental work finalized to directly test the criticalities and chances of this technology row. By means of Closed Space Sublimation (CSS) and Chemical Bath Deposition (CBD) processes, appropriate annealing treatments and specific CdTe-contacting procedures, we reached the state-of-art of this technology with about 15% conversion efficiency under standard illumination conditions in “superstrate” cells configuration both for structures deposited on 3 mm thick low-iron containing sodalime glass (SLG) and Borosilicate glass (BSG).
