Dr. Victor Yushankhai (JINR, Dubna, Moscow region) presented the report “Hybrid organic-inorganic perovskites for next generation solar cells” at Samara Center for Theoretical Materials Science.
Victor Yushankhai, doctor of physical and mathematical sciences, professor of Theoretical Physics Department, is the leading researcher of the Bogoliubov Laboratory of Theoretical Physics (BLTP) of the Joint Institute for Nuclear Research (JINR, Dubna, Moscow region). His research interests include theory of condensed matter and models of strong electronic correlations. The laboratory samples of unconventional solar cells (SC) with the energy conversion efficiency over 20% were created with direct involvement of Dr. Yushankhai. The new SC were produced of hybrid perovskites, which thanks to their specific combination of structural, chemical and physical characteristics, in Dr. Yushankhai’s opinion, are at present the best material for solar cells production.
The scientist reviewed the main principles of solar cells operation. Dr. Yushankhai provided insight into chronology of development and evolution of perovskite solar cells architecture. Their structural and chemical composition and physical properties aroused many questions.
A rapid progress in the development of heterostructure perovskite SC until the present has been mostly conditioned upon a successful empirical search of conjugated materials providing, first, an effective selection of the electron and hole carriers being photo-induced in the active perovskite layer of SC, and, second, their further transport to external metal contacts. Victor Yushankhai also defined practical pending tasks for industrial production of perovskite solar cells.
