The current-potential relations with and without illumination, quantum efficiency-wavelength relations at several potentials, the flatband potentials, the transient behavior, and the stability of seven p-type semiconductors, i.e., ZnTe, CdTe, GaAs, InP, GaP, SiC, and Si, have been measured in 1N NaOH and 1N H2SO4. The position of the photocurrent-potential relations are related to the flatband potential and the energy gap of the semiconductor. The existence of the maximum in quantum efficiency-wavelength relation is analyzed by considering surface recombination. The stability and the transient behavior are analyzed.
