摘要：
We investigate the structural, morphological and optoelectronic properties of Cu(In,Ga)S-2 thin films synthesized following the 3-stage process. The optoelectronic characteristics of the layers are observed drastically improved when the highest processing temperature is increased up to 600 degrees C. Surprisingly, these latter films are not those yielding the highest cells efficiency, probably because of non-optimized buffer/absorber interface. The best performance we have achieved within the frame of this study is 14.2 % for a bandgap of 1.65 eV, which is among the best results ever reached with these polycrystalline structures.
