“…First, we prepared the V 2 O 5 solution by the method reported previously using vanadium pentoxide powder (V 2 O 5 , 99.99% purity) purchased from Sigma–Aldrich . V 2 O 5 powder was dissolved in 2‐propanol to form 1.0 wt.%, and then we mixed V 2 O 5 solution into PEDOT:PSS (such as 20:1, 10:1, 5:1, and 1:1 by volume ratio) and stirred for 12 h. Final solution was obtained by filtering through 0.45 µm hydrophilic filter.…”

“…Poly (3,4-ethylenedioxythiophene): Poly (styrenesulfonate) (PEDOT:PSS) is regarded as state of the art HTL which is being used as a standard material for BHJ OPVs because of its high work function, easy solution process-ability, high conductivity and high optical transmittance78. However, owing to the highly acidic and hygroscopic nature of PEDOT:PSS, it favours the device degradation in number of ways910.…”

“…Impedance spectroscopy is a powerful method to not only characterize material properties but also to understand device operation as well as stability of one particular system. [48][49][50] Figure 7b depicts the typical complex impedance plan spectra of the tandem cells with different ICLs measured in the dark at zero bias. Figure 7b demonstrates the imaginary resistance over the real resistance and there are two semicircles can be found, in which it enables examination of the internal resistance of the ICLs.…”
