Resistance fitted at high frequency range in impedance spectroscopy measured at numerous light intensities from low light intensity to 1 sun illumination. Different CsPbBr3-xI x perovskite compositions (x varies between 0, 0.1, 0.2, and 0.3 in molar ratio) and hole transport materials as spiro-OMeTAD/Au (circle dots) and P3HT/MoO3/Au (triangle dots) were analyzed.
