Photovoltaic systems, nano- and microelectronics

Activity of the research group:

Physics and technology of semiconductors, implementation, modelling and metrology of semiconductor-based electronic devices, including solar cells, sensors, thermal electrical active devices. Modelling of solar cells and modules, integrated cooling of concentrator solar cells, testing of Si-perovskite tandem solar cell structures.

Recent results:

• Thermal electric circuits, implemented
• System for solar panel production forecasting using multi-domain models (measuring station on top of building D for data collection), based on ready meteorological data.
• Perovskite solar cells: long-term behaviour, stability and temperature tests. Results expected in the short term.
• Multi-domain digital twins for solar cells (industry/PV 4.0 connection)

Special infrastructure:

Clean room laboratory (Class 6, double-sided lithography, high purity heat treatment up to 1350 °C, rapid heat treatment, chemical machining station, etc. ) + outdoor wafer cutting, implantation, wire bonding • Layer deposition equipment (cathodic sputtering, vacuum evaporation) • Electron microscope/electron beam lithography • Semiconductor technology qualification measurement equipment • Emission microscope • Resonant capacitor potential/surface photovoltage mapping • Solar cell measurement (solar simulator, electrical measurement equipment)
