| description | PROBLEM TO BE SOLVED: To provide measuring device and method capable of accurately and quickly measuring the output characteristic of a photoelectric conversion device using an organic material. SOLUTION: A control unit 21 instructs a bias power supply 11 to apply a bias voltage, and acquires a measurement value from a voltmeter 12 and a measurement value from an ammeter 13 when a time not less than the sampling delay time e.g. 10 ms and not more than the time constant of a solar battery cell 10 has elapsed. In this case, the control unit 21 measures the voltage and the current at each time when the bias power supply 11 is changed stepwise in the direction from a short circuit state to an open state to obtain a first voltage-current characteristic. Then, it measures the voltage and the current at each time when the bias power supply 11 is changed stepwise in the direction from the open state to the short circuit state to obtain a second voltage-current characteristic. A computing unit 22 averages the first voltage-current characteristic and the second voltage-current characteristic to obtain a third voltage-current characteristic, and the characteristic of the solar battery cell 10 is obtained from the third voltage-current characteristic.
