Aziz Saparbaev began his scientific career when he joined the Institute of Physics of the Academy of Sciences of Uzbekistan as a junior researcher. He initiated comprehensive studies on the spectral, kinetic, and power characteristics of fluorescence in plant leaves and photosynthetic bacteria, as well as their preparations, using absorption and luminescence spectroscopy methods and pulse-amplitude modulation of exciting radiation under various conditions. He investigated the spectral and temporal characteristics of chlorophyll fluorescence in plant leaves under normal conditions and under environmental influences. Some of his research is related to bacterial photosynthesis (short and long-wave fluorescence, the influence of the molecular environment, etc.). He has worked with laser fluorescence and absorption spectroscopy systems, spectrophotometers, PAM fluorometers, and photoacoustic systems.
Currently, his main research directions include polymer/organic solar cells, perovskite solar cells, the fabrication of solar cells, investigating their optical and structural properties, and other scientific research areas. Aziz Saparbaev defended his PhD in 2020 at the Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, in Qingdao, under the supervision of Professor Renqiang Yang and Professor Shichan Bao. His research primarily focuses on investigations using spectroscopic methods, improving the photovoltaic parameters of organic solar cells, fabricating perovskite solar cells using a simple method under ambient conditions, and enhancing their stability. It is noteworthy that he studied the morphology of the active layer and exciton interface transfer behavior using advanced spectroscopic tools, which is of great importance in the development of flexible electrodes. Aziz Saparbaev has improved the photovoltaic parameters and stability of perovskite solar cells without additives, using a simple method employing solvent engineering.
To date, he has published numerous articles in high-impact factor journals such as J. Power Sources, Solar Energy, ACS Appl. Mater. Interfaces, Solar RRL, Nano Energy, Energy & Environmental Science, Organic Electronics, Chemical Engineering Journal, Applied Physics A, Journal of Materials Chemistry C, and others. Aziz Saparbaev worked and continues to work as a key scientific researcher in various projects, both before defending his PhD and after obtaining his PhD degree.
