摘要
Cu(In,Ga)Se-2/CdS/ZnO cells with efficiencies close to 19% have been obtained with films prepared by coevaporation of the elements [1]. 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 SGR (Saint Gobain Recheche) with the support of ADEME. The objective of the project is to develop high-efficiency electrodeposited CIS cells and modules. A proprietary process allows to elaborate cells with different band-gap absorbers. Band-gap materials between 1,00 and 1,5 eV have been achieved. The record cell with an absorber of 1,47 eV yields to an efficiency of 10,2% (no AR coating, total area 0,1 cm(2)). The short circuit current is 23.2 mA.cm(-3), the open circuit voltage is 741 mV and the fill factor is 59.6%. The properties of this cell are presented.
