"Martin Stolterfoht is leading the Perovskite Subgroup within the Soft Matter Physics and Optoelectronics 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."

"My research interest is mainly focused on understanding the device physics of organic and perovskite solar cells. To do so I use simulation tools, mainly drift-diffusion modeling, to understand the limitation of state-of-the-art devices. By reproducing the experimental results with the simulations we can bring a clearer picture of what happens within the device and target the main limitations for future optimization. I also use the simulation to refine our analysis of classical measurements when applied to perovskites as their ability to transport both electronic and ionic charges usually strongly influences those measurements."

"My interest lies in the fundamental understanding of working-principles and loss-mechanisms in perovskite solar cells. I try to understand the interplay between the perovskite absorber material and the adjacent organic transport layers, on time scales ranging from ps to steady-state conditions. In particular I use (transient) optical/electronical measurement techniques to assess the dynamics of charge carriers in films, single crystals and working solar cell, and to use this knowledge to optimize the multilayer architecture."

"Molecular doping is a convenient way of improving the electronic properties of semiconducting polymers, but is a technique that isn't completely understood yet. My interest lies in understanding and elucidating the fundamental processes that occur upon doping polymers with organic small molecules. I utilize a combination of UV-Vis-NIR spectroscopy, atomic force microscopy, conductivity and surface potential measurements to study the optical, morphological and electronic changes that occur with doping, and thereby deduce the doping mechanism, efficiency, kinetics, etc. in doped solutions and/or films."

"My research aims in the realization of monolithic perovskite/silicon tandem solar cells on textured wafer surfaces that are utilized for optimum light management. To pursue my goal I will develop new strategies to process inorganic-organic perovskite films on textured silicon surfaces. Additionally, my research focuses on the fundamental physical understanding of the film formation and of the transport and recombination of charges in this type of tandem structure."

"My research aim is to study the energetics and transfer of charge carriers, across an electronically hybrid interface. Tuning the energetics of the inorganic surface by applying self-assembled monolayers, mixing molecules with different electrostatic dipoles, incorporating photo-switchable molecules which results in control over the energetics at the organic/inorganic interface."

"I am interested in the various recombination processes that occur in perovskite solar cells and I try to understand the main performance limitations of these devices. Attacking these problems from a material science point of view is my main focus but I am also interested in degradation mechanism, tandem solar cells and upscaling which are key points for a commercial success of perovskite solar cells.
