AC impedance spectroscopy on Al/p-Si/ZnTPyP/Au heterojunction for hybrid solar cell applications

Unveiling the Role of H2 Plasma for Efficient InP Solar Cells

“…Using the EIS‐Spectrum Analyzer program, [ 25 ] the EECs elements’ best fitting values were calculated and are listed in Table S5, Supporting Information. The equation ( τ = RC ) [ 26 ] may be used to compute the charge carrier lifetime at different interfaces under these measured conditions The charge carrier lifetime at the Au/InP interface increased from 0.62 to 2.59 μs after H 2 plasma treatment, whereas the charge carrier lifetime deeper into the InP is found to be 10.65 μs. It was also observed previously that the minority‐carrier lifetime of InP increases as the carrier concentration reduces and reported to reach a high value of 3 μs.…”

A new cobalt(ii)meso-porphyrin: synthesis, characterization, electric properties and application in the catalytic degradation of dyes

“…This indicates that the dc conductivity is a thermally activated process. The temperature dependence of s dc can be represented by the usual Arrhenius relation: 50,51…”

Light-enhanced electrical behavior of a Au/Al-doped ZnO/p-Si/Al heterostructure: insights from impedance and current–voltage analysis

“…28 The signicant broadening of the Z ′′ peaks with increasing light intensity indicates the presence of an illumination-dependent electrical relaxation phenomenon in the studied heterojunction. 29 Furthermore, both Z ′ and Z ′′ values converge at higher frequency, possibly indicating the accumulation of space charge in the device. The relaxation time (s) of the heterojunction can be determined using the equation 30 s = 1/2pf max (5) Fig.…”
