This proposal is targeting an important research field, namely the photovoltaic conversion in the context of applications to space technology. Knowing which materials and structures are best fitted for this type of applications is of prime importance for the companies interested in producing them. Moreover, a technological path will be indicated for producing low cost structures with an enhanced photovoltaic response. The project generates opportunities for improving the experience of young researchers, members of the project team by correlating the proposed activities with ESA engineering innovative and reliable solar energy solution. They will learn new methods and techniques of scientific investigation, and part of them will use the obtained results to finalize their PhD thesis.
