The Institut Photovoltaïque d’Île-de-France (IPVF) aims at becoming one of the world’s leading research, innovation and training centres in the field of photovoltaic solar energy by federating globally-acknowledged academic research teams and industrial groups leaders in the photovoltaic sector.
IPVF intends to enhance the performances and competitiveness of photovoltaic cells and to develop new breakthrough technologies.
Against a backdrop where almost all photovoltaic modules are produced outside Europe (97%), advances must be founded on technological breakthroughs and innovations.
To date, the predominant technology, silicon, is limited theoretically to 29% efficiency, i.e. its ability to transform photons into electricity. Yet, tandem technologies, which consist in associating two cells made from different yet complementary materials could theoretically deliver efficiency of over 42%. Based on cutting-edge industrial production processes which form a breakthrough, they offer opportunities for intellectual property development and industrial positioning for newcomers to the sector, in a market estimated to stand at several hundred billion dollars per year by 2035. A myriad of technological obstacles still need to be overcome as regards the choice of materials to be used, large-scale production processes and production costs. Although several international institutes have already initiated ambitious programmes in this field; in just 4 years, IPVF has already obtained promising results in this area.
