To enhance the efficiency of tin halide perovskite solar cells (PKSCs), researchers addressed defects like Sn4+ and iodide vacancies by introducing copper iodide (CuI) doping. A preprocessing method for CuI improved perovskite layer quality, resulting in efficiency increases from 9.8% to 13.1% for P-I-N structures and 9.4% to 10.5% for hole transport layer (HTL)-free structures. These doped tin-PKSCs also exhibited improved stability, retaining 75% of their initial power conversion efficiency after 102 days of storage.
How Paios was used
Intensity-modulated photovoltage spectroscopy (IMVS), Intensity-modulated photovoltage spectroscopy (IMPS), Transient photovoltaic voltage (TPV), and Transient photovoltaic current (TPC) were carried out via PAIOS software.
