Clustering of CdS nanocrystals during evaporation of the Langmure-Blodgett matrix and influence of matrix thickness on the parameters of the resulting clusters have been investigated. Information about the size and spatial distribution of nanocrystals and clusters has been obtained using atomic-force microscopy. It has been found that at thickness of the matrix less than 6 nm the free-standing nanocrystals...
The formation of low resistance ohmic contacts on p-type CdTe is a major challenge for the superstrate solar cell the dominant device configuration for this technology. It is even a greater challenge for the substrate configuration, since the back contact material is deposited first and is therefore influenced by subsequent high temperature fabrication processing. In this paper, the structural and...
Cu(In,Ga)Se/sub 2//CdS/ZnO cells with efficiencies close to 19% have been obtained with films prepared by coevaporation of the elements. Electrodeposition has the potential to become a suitable method for large production of CIGS solar modules. In this paper, we present the results of an on going collaboration project, between CNRS-ENSCP, EDF (Electricite de France) and SUR (Saint Gobain Recheche)...
