Solar energy is already the most cost-effective option for new power plants in many parts of the world. The challenge is to find the right technologies that will allow us to further reduce the cost of solar energy and make efficient use of this volatile energy source.

- This means to absorb large amounts of overproduction when the sun is shining, but to provide solar power even when it is dark! The Renewable Energy Division is engaged in applied energy research in the field of photovoltaics to accompany the structural change in our energy system. The work spectrum focuses on combinatorial highly automated materials research, own concepts and manufacturing processes for solar modules based on printed semiconductors (e.g. OPV), methods for the characterization and optimization of solar modules and systems, as well as smart grid technologies for the integration of volatile current into the low-voltage grid. The Erlangen site also has an accredited testing laboratory for photovoltaic modules. In the only independent, accredited testing laboratory for photovoltaics in Northern Bavaria, experts, insurers, plant operators and system houses can have solar modules examined and tested.

Research Focuses:

  • Combinatorial material development
  • Plant development for automated materials research and automated measurement methods
  • Big Data Methods and Automated Learning
  • Printed Photovoltaics
  • Upscaling and module development for flexible PV
  • Process development for print and laser processing

  • Test laboratory - development of new test standards
  • Investigation of PV modules, storage devices and Smart Grid components in the field laboratory and low-voltage grid
  • System integration of renewable energies into the low voltage grid
  • Characterization, modeling and system integration of Smart Grid technologies

Fields of Research

Solar Factory of the Future

solar factory

In the „Solar Factory of the Future“ 3rd generation solar modules are developed, which may be manufactured continuously with roll-to-roll processing like digital printing or coating techniques in combination with laser processing.The technical facility at the Energie Campus Nürnberg offers an open development platform for industrial partners in order to develop printed PV technologies, as well as prototyping capabilities for the integration of printed PV in various applications like building integrated photovoltaics and mobile systems.

AQUAM – Quality management system for PV systems

The aim of the project is to develop a model for predicting the performance of installed photovoltaic modules under operating conditions, so that no disassembly or transport of the PV modules is required for inspection. In The investigations focus on modules with non-obvious defects and optically conspicuous phenomena. In addition, it is of interest how defects and the performance under various environmental stresses ...and you're not gonna behave. The PV module is simultaneously exposed to optical, thermomechanical and chemical alternating stresses, but also to extraordinary events such as hail. These influences have different Effects on the material mix of a PV module. With the aid of imaging methods (electroluminescence and thermography) and simulations, the ageing behaviour of installed PV modules is investigated and quantified. and found a decision basis for module and plant evaluations.
