Photovoltaics (PV) is a key cornerstone technology for the transformation of our energy system. In this business area, Fraunhofer ISE specializes in research topics in four areas: Silicon Photovoltaics, III-V and Concentrator Photovoltaics, Emerging PV Technologies and PV Modules and Power Plants. With its many years of experience and its state-of-the-art laboratories and equipment, Fraunhofer ISE is ideally positioned to provide expert R&D services and continue its advances in the field of photovoltaics in the future.
Within the business area of photovoltaics, our largest area of R&D is in the field of Silicon Photovoltaics. With a share of 90 %, this technology dominates the market and continues to demonstrate large potential for cost reductions. The main research themes we address are material development, cell architectures and production technologies, module technologies, electricity yield and quality assurance.
In III-V and Concentrator Photovoltaics, our central aim is to further develop these highest efficiency solar cells based on III-V semiconductors for use in both space applications and terrestrial concentrator systems. Fraunhofer ISE currently holds the world record efficiency of 46 % for this type of solar cell. Concentrator PV module development as well as other applications such as Power-by-Light supplement the Institute’s portfolio.
Organic and Dye Solar Cells – including the field of perovskite solar cells – belong to the emerging technologies and future concepts in the field of photovoltaics. At Fraunhofer ISE, we carry out R&D in up and down conversion, photonic structures, etc. Tandem structures on silicon are investigated with the aim of further optimizing the PV efficiency.
R&D services in PV Modules and Power Plants comprise module development with respect to optimum efficiencies, reduced costs and maximum reliability as well as special applications such as building integration. From the planning phase through to continuous system operation, Fraunhofer ISE offers its services in quality assurance of PV power plants.
