Unraveling Charge Carrier Recombination Dynamics in Semi-transparent Perovskite Solar Cells: Intensity and Temperature Dependent Analysis

Semi-transparent perovskite solar cells (ST-PSCs) have shown the potential in building-integrated photovoltaics (BIPVs) as an alternative to conventional transparent photovoltaics like CdTe, CIGS, or organic solar cells, due to their high light-utilization efficiency (LUE). ST-PSCs have achieved significant strides through device engineering, but their performance under real-world conditions, such as varying temperatures and intensities, remain a challenge for their commercialization. In this study, we have explored the charge transport kinetics and recombination mechanisms using temperature and intensity dependent electrochemical impedance spectroscopy (EIS), J–V characteristics, and SETFOS simulations. These temperature and intensity dependent analyses offer insight into the relationship between temperature, efficiency, ionic transport, diffusion, and recombination losses in ST-PSCs, helping in designing thermally stable and better performing ST-PSCs for real-world applications.
