Summary / Abstract: With the rise of perovskite-based solar devices, Solar PV has not only reinforced its central position in the renewable energy transition for electricity generation, but it has also reinvigorated the race for untapped integrated power generation. To succeed in producing cheaper and more affordable electricity, capacitive techniques are essential to understand the transitional properties of solar devices and their impact on the short- and long-term performance. In this publication, we present a study on combined admittance spectroscopy measurements at different biases that are commonly used to characterize metal–oxide–semiconductors and pn-junction devices with the same approach being already tested and validated on CIGS devices[1]. This study generalises the use of this technique to other PV technologies such as perovskites and organic solar cells and identifies correlations among the different structures and material properties.
