Dr. Artem Musiienko has earned a prestigious Maria Skłodowska Curie Postdoctoral Fellowship for his research project HyPerGreen. In the group of Prof. Antonio Abate, HZB, Musiienko will explore and improve lead-free perovskite solar cells with the goal to increase their efficiency to more than 20 %.  

Musiienko completed his doctorate in 2018 at Charles University in Prague on a topic related to semiconductor physics and subsequently worked there as a research assistant. In 2020, he moved to the HZB Institute for Silicon Photovoltaics, where he investigated defects in halide perovskites, among other things. He has contributed significantly to the enormous increases in the efficiency of halide perovskite solar cells, for which the HZB is now internationally renowned.

"However, those highly efficient halide perovskites contain small amounts of lead, a toxic heavy metal that must not be released into the environment," says Musiienko. But lead can be replaced with tin, which has been shown to be non-bioavailable and therefore harmless. So far, however, the efficiency and stability of tin perovskite solar cells are much lower in comparison. Musiienko now plans in his HyPerGreen project to significantly improve tin perovskite solar cells and to explore the mechanisms that limit charge transport in the bulk and at the interface of these materials. Musiienko will use the novel Photo-Hall method, he has recently developed at HZB. “At the moment, together with HZB, we patent this method”, he adds. The method is based on a combination of magnetic field and light and can be used to explore charge transport parameters and limiting factors of the material, which were unreachable otherwise. His goal is ambitious: In his projects he is aiming for efficiencies of over 20 %, a big step forward from the current record of 14.6 % (1).

    Watching indium phosphide at work
    Indium phosphide is a versatile semiconductor. The material can be used for solar cells, for hydrogen production and even for quantum computers – and with record-breaking efficiency. However, little research has been conducted into what happens on its surface. Researchers have now closed this gap and used ultra-fast lasers to scrutinise the dynamics of the electrons in the material.
