Hitherto a number of circuits for current (1) - voltage (VI characterization of solar cells have been developed. But these circuits do not have the frequencv stability and versatility for carrying out I-V studies in dark as well as under illumination of solar cells. A circuit tor logarithmic current versus voltage has been developed which makes use of IC 8038 oscillator and 3513 power amplifier for best frequency and power performance. Alsa a Teledyne Phillbrick 4362 precision logarithmic operator has been made use of for conversion to log I accurately. The circuit has been successfully tested. The functional parameters of a standard silicon solar cell such as reverse saturation current (I,), the diode factor (n), the open circuit voltage (V,,i, the short circuit current 11,) have been recorded.
