Laboratory of Optoelectronic Materials Physics
The laboratory of optoelectronic materials physics focuses on the studies of fundamental physical properties of semiconductors for optoelectronic applications such as solar cells, lasers, diodes, sensors etc. Our research infrastructure enables to explore the band structure, crystal and defect structure, phase and elemental composition, morphology, electrical and optical properties of the materials and devices.
Our current research is focused on the fundamental studies of different novel absorber materials for solar cells, for example Cu2ZnSn(S,Se)4, Cu2SnS3, Cu(In,Ga)Se2, SnS, CdTe, SnSe etc, and two-dimensional materials such as WS2, MoSe2 etc. The last mentioned have versatile applications in addition to photovoltaics, namely photonics, sensors etc. In addition to the inorganic semiconductor based structures, hybrid structures combining the advanatges of inorganic and organic semiconductors are being developed and studied.
Our laboratory includes also the outdoor testing center of photovoltaic modules, where it is possible to monitor the dependence of modules' output parameters on the environmental conditions. We can estimate the performance of photovoltaic modules at different climatic locations, analyze the energy rating models and calculate the cost effectiveness of photovoltaic systems.
In addition to the research, we are offer materials characterization service for all interest groups.
