Investigation of Cu2znsn(S,Se)4 Solar Cells with Nano/Micro Structures Prepared by Dynamic Shadowing Growth

By combining substrate positional control and oblique angle deposition, dynamic shadowing growth (DSG) is a simple and versatile nano/micro-fabrication technique based on the self-shadowing effect during a thin-film deposition process. Applying DSG nano/micro structures in renewable energy applications will be our major tasks. In addition, Kesterite-based solar cells are important semiconductors with significant potential for applications in the next generation of photovoltaic devices in recent years, owing to the reduced toxicity and greater abundance of their constituent elements. Therefore, the aim of this project is to develop high efficiency Kesterite-based solar cell with 8 % efficiency by evaporation technique with DSG technique. Under a simulated 1-sun condition and light incident angle increased to 60°, cells with nano/micro structures enhanced the short-circuit current density by 35%. The achievements can make substantial progress in developing sustainable Kesterite-based solar cells providing environmental and manufacturing benefits.
