In the last decade, perovskite semiconductors have triggered an unparalleled hype in solar cell research resulting in a rapid increase in power conversion efficiency up to 25%. In part this is due to the urgent need to find renewable and cheap energy resources as well as their outstanding and partially unprecedented opto-electrical properties. Another major driving force for the rapid evolution of perovskite PV is the possibility to combine perovskites with emerging and well established PV technologies to tandem solar cell applications promising next generation multijunction solar cells. Tandem solar cells are not bound to the fundamental thermodynamic limitations of single junction cells and create opportunities to harvest solar energy much more efficiently and at lower cost. In combination with silicon, perovskite multi-junction cells already demonstrate efficiencies (29.1% NREL chart) that outperform the best single-junction silicon cells (26.7%). Despite this success, today there remain many open questions with respect to the opto-electronic properties of perovskites, recombination losses and long-term stability, opening new exciting research opportunities.
The Perovskite Group at the University of Potsdam aims at the development of highly efficient, stable single and multi-junction perovskite cells through a fundamental understanding of charge transport and recombination processes. The research activities include several cutting edge research topics as shown below. The group is well connected with many collaborations worldwide and is part of HyPerCells - a joint graduated school of the University of Potsdam and the Helmholtz Zentrum Berlin that aims at the development of silicon/perovskite tandem cells.

Martin Stolterfoht is leading the Perovskite Subgroup within the Soft Matter Physics Group at the University of Potsdam. He completed his Master’s degree in Physics at the University of Graz, Austria in 2012 and obtained his Ph.D. at the University of Queensland, Australia in 2016. His research is focused on providing a fundamental description of thin-film solar cell operation and charge recombination processes from picoseconds to steady state through electrooptical measurements and numerical modeling. He also aims at improving perovskite single and multijunction solar cells through the identification and suppression of recombination losses. (Contact: email@example.com)
