Title : A deep dive into p-i-n rudorffite solar cell architectures for optimizing solar energy conversion


A lead-free and efficient solar cell is essential to the rapidly evolving field of photovoltaic research. Silver bismuth iodine compounds, which are nontoxic and environmentally stable, are considered promising photovoltaic candidates, due to their low cost and high photoelectric conversion efficiency. In this presentation we will focus on the simulation results of Rudorffite-based solar cells using the SCAPS-1D simulation program, specifically Ag3BiI6, Ag2BiI5, AgBiI4, and AgBi2I7. In the study, Ag3BiI6 solar cells showed the highest efficiency compared with Ag2BiI5, AgBiI4 and AgBi2I7. In solar technology, Ag3BiI6's superior energy band alignment has a significant impact on future research and development. Rudorffite base devices were also evaluated in relation to their generation rate, recombination rate, capacitance-voltage, current density-voltage, and quantum efficiency characteristics based on their absorb and ETL thickness, series resistance, shunt resistance, and operating temperature. Finally, we discuss critical fundamental questions that need to be addressed in order to progress in this area.

Audience Take Away Notes:

  • A SCAPS-1D simulation is applied to analyze the performance of various Rudorffite solar cells
  • There are several factors that affect the efficiency of lead-free solar cells, including the thickness of the layers, the concentration of doping, and the density of defects
  • Hole Transport Layer (HTL) and Electron Transport Layer (ETL) impact the overall efficiency of solar cells
  • Enhance the design and efficiency of solar cells by utilizing the findings of SCAPS-1D simulation
  • Research outcomes can lead to more efficient and cost-effective solar cell designs, possibly increasing the sustainability of energy
  • A practical solution to increasing the efficiency of solar cells may be found by researchers, simplifying the design process and enhancing the job's efficiency
