The work of this department focusses on the use of light as a tool in novel technologies for energy-efficient lighting, energy generation (photovoltaics), signal and data transmission, sensor technology and material processing. In addition, the corresponding manufacturing methods are developed and integrated into industrial production processes.

• Optical fibres: waveguides
• Lighting: colour mixing, light control (diffractive and refractive optical elements), light coupling and light transmission (e. g. for solid-state lighting, LED)
• Photodetectors: light guidance in modules and colouring; improved efficiency in photovoltaic modules / technology
• Optical components & systems: simulation, design and manufacturing of optimized optical components (diffractive, refractive, freeform micro-optics)

• Flex!PV_2.0: technologies for expanding the functionality and performance of flexible kesterite- and perovskite-based PV
• Green Photonics: Solutions for a sustainable life with light: fields of application are lighting, optical sensors and photovoltaics
• Kollsens: Bionische Kollisionssystem für unmanned aerial vehicles
• Next_Pro_Foil: Novel extrusion processes for next generation light management films
• PERMASOL: perovskite materials for efficient solar cells
• PHABLABS 4.0: PHotonics enhanced fAB LABS supporting the next revolution in digitalization
• SiTaSol: Application relevant validation of c-Si based tandem solar cell processes with 30% efficiency
• ThermOLED: thermal behavior of OLEDs: a holistic view.
