The project’s key issue is to enhance efficiency and reduce energy conversion losses by optimizing materials and BC electrode structures.

Scientific supervisor: Ph.D., Associate Professor, Omarova Zhansaya

Expected and achieved results: Optimized perovskite material structures with varying compositions will be developed, and their electronic and optical properties, including band gap, absorption, and refractive index, will be determined. The impact of composition and structure on the efficiency of BC PSCs will be analyzed. Models will be created to accurately evaluate optical characteristics and energy distribution, as well as charge carrier generation rates for performance prediction. Key parameters of solar cells will be optimized to enhance efficiency and energy yield. The economic and energy feasibility of BC PSCs will be assessed, along with a comparative analysis to determine their competitiveness in the photovoltaic market.
