After nearly 40 years of R&D on solar cell materials and devices, Professor Hegedus is now working to promote PV integration onto the nation’s electric grid. To accomplish this, his work is focused on overall grid modernization at the local distribution level using microgrid simulation, power conversion hardware studies, and policy recommendations. Professor Hegedus also teaches classes on Photovoltaic Technology and on Microgrids. He is the co-editor of both editions of the Handbook of Photovoltaic Science and Engineering (Wiley, 2003, 2011).

Research Interests

  • Apply technologies like smart inverters and batteries to enable significant increase in the integration of PV on the grid without causing instability
  • Interoperability, communication, and cyber-security of distributed generation devices connected to the grid
  • Microgrid simulation, design and implementation
  • Assist policy makers and regulators to understand the need for grid modernization to integrate more renewable energy
  • Investigate new applications for PV modules like charging Electric Vehicles and Agrivoltaics (growing crops under movable solar array that provide controlled shade and sun)
