In the solar cell  evaluation system, the 7461P is capable of shutter open/close control on the solar simulator by using the ambient tempeature measurement and digital output functions.
Since the conversion efficiency of a solar cell is influenced by bias application time, measurement by pulse application is effective in finding the true conversion efficiency. By using the pulse sweep function of the 6241A/6242, the I-V curve can be measured at high speed. Furthermore, by changing the pulse width, the change in characteristics depending on the application time can be measured easily. In addition, the two slope linear sweep function that can switch the step value during measurement enables measurement from the vicinity of voltage at the peak power point to open-circuit voltage in small steps.
