The development, production and characterization of semiconductor thin films and nanostructures, especially on the basis of silicon and transparent conductive oxides, for novel devices such as optical sensors and solar cells on various substrate materials characterizes the profile of the Photovoltaic Systems working group.
The goal is the development and application of scalable technologies for the production and modification of novel semiconductor thin films and thin film systems, including nanostructured surfaces, for a broad range of applications, especially in medical and environmental technology and in the field of security.
The basis is a broad spectrum of coating processes such as CVD, PECVD, electron beam evaporation, sputtering, ALD and inkjet printing as well as wet-chemical deposition methods. Combined with laser processes and wet chemical etching, thin film systems and structures as well as functional surfaces with special properties for sensory applications and power generation are obtained.
The research topics of the Photovoltaic Systems working group are scientifically based on solid state physics, light-matter interactions and nanotechnology. For the technological implementation, the working group can draw on various laser systems and various coating and structuring processes.
The broad application spectrum of the Photovoltaic Systems working group addresses in particular questions in the field of environmental and medical technology as well as in the field of safety.
