CdTe/CdS thin film solar cells, since they are made with easily scalable techniques such as sputtering and closed space sublimation, can be considered particularly suitable to be produced on a large scale. Besides, we developed a new process which is simplified in respect to the normally used processes, since it is dry and it does not make use of any acid. Furthermore, CdCl2, used for CdTe treatment, has been substituted with a non toxic gas, namely HCF2Cl. Back contact is done by a procedure that allows to make stable cells. An efficiency close to 16% is obtained on 1 cm2 area with this process. In order to scale up this new process to an industrial production, a new company, named ARENDI, with the participation of the Marcegaglia industrial group, IFIS Bank of Venice, the contribution of Ministry of Environmental and the scientific support of the thin film group of the University of Parma, has been constituted. The line is starting to be constructed near Milan and will be ready within two years. The size of the module will be 60x120 cm2 and the production capacity of the line should be around 15 MW/year.

Abstract
CdTe/CdS thin film solar cells, since they are made with easily scalable techniques such as sputtering and closed space sublimation, can be considered particularly suitable to be produced on a large scale. Besides, we developed a new process which is simplified in respect to the normally used processes, since it is dry and it does not make use of any acid. Furthermore, CdCl2, used for CdTe treatment, has been substituted with a non toxic gas, namely HCF2Cl. Back contact is done by a procedure that allows to make stable cells. An efficiency close to 16% is obtained on 1 cm2 area with this process. In order to scale up this new process to an industrial production, a new company, named ARENDI, with the participation of the Marcegaglia industrial group, IFIS Bank of Venice, the contribution of Ministry of Environmental and the scientific support of the thin film group of the University of Parma, has been constituted. The line is starting to be constructed near Milan and will be ready within two years. The size of the module will be 60x120 cm2 and the production capacity of the line should be around 15 MW/year.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
