Solar Systems & Equipment (ITALY)

Solar System & Equipment is a company founded in 2001 with the aim to develop and transfer PV technology. Among the founding members there are the researchers who developed an innovative process for the production of photovoltaic modules based on CdTe/CdS thin film. SSE owns the patents that led to the development of the "Arendi"  project. This project is aimed to build a 18 MW per year manufacturing plant which will be ready in mid-2009. SSE is also involved in pre-competitive industrial projects on the architectural integration of photovoltaic modules. One of this project is focused to develop devices by using commercial ceramic tiles as substrates for CIS-based photovoltaic modules.
Besides SSE is studying new materials to be used as transparent conducting contact in thin film CdTe photovoltaic modules. The company is located in Pisa, Italy, via S. Maria 19.

Role in the project

SSE is mainly involved in WP4 as a supplier of solar cells for all the needs of project partners. The activities will be divided into two macro-areas. The first one consists in the realization of a CdTe/CdS thin film solar cell in the superstrate and substrate configuration in which the CdTe layer is deposited by Close-Spaced Sublimation (CSS). The second case concerns the realization of a new process, based on innovative intermetallic precursors deposited by sputtering, in order to obtain a highly efficient CuInGaSe2/CdS solar cell on flexible substrates.

The key personnel to be involved in the project activity includes:

Alessio Bosio has been working on photovoltaics since 1984. Since then, he is co-author of more than 60 papers on polycrystalline thin film solar cells based principally on two family of materials: CdTe and CuInSe2. These articles are published in international refereed ISI journals and conference proceeding. He participated to almost all the European Joule Projects in the research group directed by Prof. Nicola Romeo. He is considered an expert in thin film deposition techniques, such as Electron Beam Gun (EBG), RF and DC magnetron sputtering, Close Spaced Sublimation (CSS) and Vacuum Thermal Evaporation (VTE). He projected and optimized some deposition equipment like CSS and Selenization Chamber Reactor that are used to obtain high efficiency CdTe/CdS and CuInSe2/CdS based thin film solar cells. He teaches "Thin Film Deposition Techniques" at the Science Faculty of the University of Parma since 1995.

Nicola Romeo has been working on photovoltaics since 1975. He made the first CuGaSe2/CdS solar cell with a 5% efficiency. Since then, he has published more than 100 works on CdTe/CdS and CuInGaSe2/CdS thin film solar cells. He participated for 8 years to the Energy Finalized Project and to almost all the European Joule Projects. He was able to obtain CdTe/CdS  and CuInSe2/CdS thin film solar cells with efficiency around 15%. He is director of a research group since 1976 and he teaches Physics at the Science Faculty of the University of Parma since 1970 and he is full professor of physics at the University of Parma since 1987. As an expert in CdTe/CdS thin film solar cells, he delivered several invited talks and in particular an invited talk to the European Material Science Conference held in Strasbourg (France) on the back contact in CdTe/CdS thin film solar cells.
In 1981 he has worked for 9 months as a visiting professor at Stanford University.
He has been a member of the scientific committee of many European Energy Conference and session chairman in several international conferences.
