Joint Solar Program III

The aim of the Joint Solar Program III is to develop fundamental knowledge of hybrid tandem solar cells with a conversion efficiency of 30% or more. 

Two PhD students will be working at TU Delft:

  • Professor Miro Zeman is leading the Advanced architectures for hybrid tandem solar cells project. The goal of this project is to fundamentally understand, develop and demonstrate architectures of perovskite/c-Si tandem solar cell structures for obtaining maximum energy conversion efficiency.
  • Professor Arthur Weeber is leading the High-Efficiency c-Si solar cells project. The focus of the project is to elucidate fundamental mechanisms of advanced passivating structures and integrate them in the solar cell for enabling more than 25% efficient c-Si solar cells.


  • Dr. Miro Zeman, Associate Professor
  • Dr. Olindo Isabella, Associate Professor
  • Arthur Weeber, Part-time Professor

Partners: This project is a cooperation of Delft University of Technology, Eindhoven University of Technology, University of Amsterdam and research institute AMOLF. 

Funding: The JSPIII program will run in the period between 2017-2022. The total budget of the program is 2.85 million Euro. The largest contribution of 2 million Euro comes from the NWO, 0.5 million Euro was contributed by Shell company, the rest is supported by Tempress, Levitech, Exasun and Eternal Sun.
