In this paper we have concentrated on the system to determine the micro second ranged lifetime of solar cell, where OCVD (open circuit voltage decay) technique is used with AVR Micro-controller. Using a contactless instrument, the photo conductance is measured in a quasi-steady-state mode during a long, slow varying light Pulse and flashing of the LED array can be changed by changing the frequencies through pulse rate. AVR micro-controller is connected with the computer and entire system is controlled by the software. Life time of the solar cell is changed by changing the value of pulse in the program. The effective lifetime (τ) of solar cell is obtained from the slope of the decay curve which can be seen in the C.R.O. But here AVR is interfaced with LCD display so that, the life time (τ) of the solar cell can be seen directly as a numerical value on the LCD. The life time (τ) is one of the most important parameter for the characterization of solar cell, used in the preparation of the power electronic devices and photovoltaic solar cell.
