Opis:: Electrochemical properties of a zinc/polyvinyl alcohol-potassium hydroxide/carbon cell have been investigated. In this cell, PVA-KOH gel has been used as an electrolyte with PVA/KOH wt.% ratio of 60:40, while zinc and carbon rods served as electrodes. The cylindrical glass vessel of length 3.0 cm and of diameter 2.0 cm has been used as a cell compartment. The current-voltage characteristics and open circuit voltage-time, charge voltage/current-time and discharge voltage/current-time studies have been done. The open circuit voltage has been observed for 160 h. It has been found that the cell shows stability and is rechargeable, too.

Opis:: Electrical characteristics of the heterojunction fabricated by thermal deposition of copper phthalocyanine (CuPc) on an n-silicon substrate have been investigated. The frequency has significant effect on capacitance (C), conductance (G) and series resistance $(R_{s})$ interface states $(D_{it})$ of the junction. Measured capacitance and conductance were corrected for $R_{s}$. The conductance technique was used to measure the density of the interface states. This method revealed the value of the interface state density distribution for the Au/n-Si/CuPc/Au interfaces of the order of $10^{12} cm^{-2} eV^{-1}$.
