Forschungszentrum Jülich

Overall presentation

orschungszentrum Jülich is an interdisciplinary, publicly funded research centre with a staff of about 4.600 members working on the areas of health, energy and environment, and information technology. Main mission is Research for a sustainable future determines activities at Jülich in the field of energy and environment. How can society be supplied with energy on a global scale? An environmentally friendly solution to this problem will only be possible if we succeed in using fossil fuels more efficiently in the future, in refining stationary storage technologies, in tapping completely new energy sources, and in increasing the proportion of renewable energies in the energy mix. This is only possible if energy and climate research are integrated and if researchers from different disciplines collaborate.


  • Jülich will be in charge of conformal ZnO:Al deposition and nano-texturation onto embossed glass (WP3)
  • Implementation of novel modulated surface textures in thin-film silicon solar cell technology involving reduced absorber layer and finally demonstration of improved light-trapping design (WP5)
  • Characterization of optical, electrical and scattering properties of ZnO:Al on modulated surface-textured substrates (WP6)

Further information

Institute of Energy and Climate Research (IEK5: Photovoltaics) is one of the institutes at Forshungszentrum Jülich that concentrated its work on thin-film silicon solar cells and related materials. The basic strategy of the IEK5 is the research and development of thin film solar cells based on amorphous and microcrystalline silicon using the processes compatible with industrial applications. Based on fundamental research on the electronic materials and light confinement, new concepts are developed and applied in small area solar cell devices (1cm2). IEK5 scales up this technology from lab-type equipment to fully industry compatible processes on medium size (0.1 m²) in-house and in collaboration with industry to several square meters. Additionally, IEK5 is experienced in nano-optical, electrical and structural characterization of transparent conductive oxide layer (TCO) and silicon films as well as simulation of light scattering of optical components and full solar cells and modules.
