Experimentalapproaches for the performance improvement of C d S / C d T e solar c e l l s produced by Screen-Printing and S i n t e r i n g technique h a v e been performed. T h e b i a s v o l t a g e dependence of f i l l factor and performance degradation related on the lattice m i s m a t c h between C d S and C d T e are much improved b y reducing the C d C 1 2 residue in the sintered C d S film and optimizing the C d T e sintering condition especially the sintering temperature and the h e a t -u p rate. 8 498 0160~8371/90/0000-0498 ' $1.00 1990 IEEE
