Mark KHENKIN

Dr Mark Khenkin completed his MS and PhD degrees at Moscow State University with a specialization in semiconductor physics. He continued his research at Ben-Gurion University (Israel).- prof. E. Katz’s group.- which was focused on the stability of perovskite solar cells, especially their outdoor stability. In 2019 he joined Helmholtz-Zentrum Berlin (Germany) where he continued to develop this topic in the Outdoor Performance Group. This work includes topics of device encapsulation, tracing the impact of environmental factors on the cell power output and development of accelerated indoor ageing procedures. Identification of the degradation modes in perovskite devices that are relevant for real-world scenarios is the key to improving their operational lifetime and designing technology-specific testing procedures.

Collaboration within TAPAS project offers a great get Mark's research to a new level through samples and ideas exchange with project partners and upgrades for HZB's outdoor setups that enable long-term outdoor tracking of the small area single junction and tandem devices.

Mark’s research field is also strongly connected to the ISOS community, that studies organic and hybrid PV stability. He was part of regular conferences, past and ongoing community experiments and the development of the stability consensus statement that was reported in 2020 and that is the topic of the Viperlab 's talk offered on Jan 17 th, 2024.
