Laboratory for Chalcogenide Photovoltaics (LCP)

The LCP group is dedicated to the material sciences of chalcogenide compound semiconductors, e.g., Cu(In,Ga)(S,Se)2 (Chalcopyrites) and Cu2ZnSn(S,Se)4 (Kesterites), and their application in solar cells and commercial photovoltaic modules. Our scientific interest is focused on the fundamental physics of heterojunction solar cells and on the exploration of efficiency-limiting properties of the involved materials and interfaces with particular attention to lateral and vertical inhomogenieties and matastable phenomena. To address specific problems we employ a broad spectrum of diagnostic tools comprising methods from the following categories:

  • Structure analysis

  • Chemical depth profiling

  • Electron and scanning probe microscopy

  • Optical characterization

  • Electronic thin film characterization

  • Electrooptical and imaging device characterization

  • Optical simulation (OptiSim)

  • Device simulations.

Currently we launch a facility for deposition of chalcogenide thin films and functional layers relevant for solar cell applications. The equipment for processing chalcogenide films is still under evaluation.

Further activities of the LCP group:

  • Cuprous oxide heterojunction solar cells

  • Perovskite solar cells (with group Borchert)

We offer our expertise equipment as service with costs to companies and commercial enterprises. For further details please follow this link.
