The Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) has announced a new R&D goal to develop a commercially viable thin-film-on-silicon tandem solar cell with 30% conversion efficiencies.

SERIS researchers will collaborate with Nanyang Technological University (NTU) and Campus for Research Excellence and Technological Enterprise (CREATE) of NRF on both III-V and perovskite materials, while SERIS will develop optimized silicon bottom cells.

Dr. Lioz Etgar obtained his Ph.D. at the Technion'Israel Institute of Technology, and completed his post-doctoral research with Prof. Michael Grätzel at EPFL, Switzerland. Dr. Etgar was the first to demonstrate the possibility to work with the perovskite as light harvester and hole conductor in the solar cell which result in one of the pioneer publication in this field.

Dr. Etgar is now leading the Perovskite solar lab in the Hebrew University in Jerusalem, Israel. Etgar's research group focuses on the development of innovative solar cells. Etgar is searching for new excitonic solar cells architectures while designing and controlling the inorganic light harvester structure and properties to improve the photovoltaic parameters. Etgar was kind enough to answer a few questions we had for him.
