AP27508001 – Study of the stability of perovskite materials under low-temperature conditions (15-100K) for further application in space research
Objective of the project – The goal of this project is to study the stability of new crystal structures of perovskite material under simulated space conditions, in particular extreme vacuum (P = 10-8 Torr) and low temperature (T = 12K), with a view to their potential use in space technology.
Relevance: Perovskite solar cells (PSCs) have great potential, but their efficiency is limited by instability caused mainly by humidity and oxygen exposure. These factors lead to hydrolysis, photo-oxidation, and degradation of the material. In space, the absence of moisture and oxygen can reduce these negative effects and improve stability. Initial studies have shown the feasibility of using PSCs in space applications. Current research focuses on radiation resistance and degradation mechanisms under simulated space conditions.
Scientific supervisor: Ph.D., Professor, Yerezhep Darkhan
Expected and achieved results: New samples will be exposed to extreme conditions simulating the space environment, followed by comprehensive characterization using optical absorption, microscopy, Raman spectroscopy, FTIR, and SEM. Stability will be evaluated over time by measuring electrical impedance and current–voltage characteristics under high vacuum (10⁻⁸ Torr) and low temperature (12 K). These experiments will confirm the initial properties and behavior of the synthesized materials. The collected data will enable a detailed assessment of perovskite stability. Based on the results, recommendations will be developed to optimize synthesis conditions and obtain stable, commercially viable materials.
