Abstract Results are reported to describe the influence of additives on the photoelectrochemical properties of the liquid junction α-HgS/electrolyte. The semiconductor electrodes were prepared by sublimation of α-HgS on Au substrates. The electrolyte was modified by additives such as Cl-, Br-, J-, and CN- ions. It was found that these anions play an important role in determining the flat band Vfb and the transition potential Vtr. Generally, both the nature and the concentration of the additives affect Vfb and Vtr.The results are interpreted in terms of contact adsorption of the used anions. It is further indicated that the adsorptive properties can be correlated to a possible chemical reaction of mercury cations with halide anions to form insoluble layers at the surface.

AbstractCarrier drift mobility is an important physical constant in the charge transport process of organic solar cells (OSCs). Although time-of-flight and space-charge-limited current techniques have been frequently utilized for mobility measurements, the validity of a new method using modulation photocurrent spectroscopy is discussed in this contribution. The advantages of this method are its applicability to working OSCs with optimized device structures and the simultaneous determination of the electron and hole mobilities. These features make it possible to study the relation between the mobility balance and the solar cell characteristics, such as the power conversion efficiency, using only a single working OSC; hence, it is not necessary to fabricate electron-only and hole-only devices for mobility measurements. After carrying out numerical simulations to examine the validity of this method for mobility determination, the dependence of the mobility balance on the mixing ratio of the electron-donor and –acceptor materials is presented.
