Abstract

With the increased research work on improving the efficiency and reliability of perovskite solar cells (PSC), the importance of different quantification techniques and accurate characterization to optimize the material and device structure is imminent. The electroluminescence (EL) imaging technique enables new methods for identifying the dislocations, grain boundaries, defects, functioning and non-functioning areas, etc., in PSCs. This technique had been effectively used for crystalline-based solar cells/modules in past years but presented challenges for PSCs. This is the first practical study that demonstrates the steady state EL imaging technique for PSCs. This work provides the experimental setup, results and interpretations quantified from the EL images and their association with solar cell parameters for the lead halide solution-based glass substrate PSCs. Finally, a correlation is shown between the maximum EL Efficiency to their cell properties.
