EVALUATION METHOD OF PHOTOELECTRIC CONVERSION DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain an easy and accurate evaluation method of a photoelectric conversion device formed by forming at least a photoelectric conversion layer and a conductive layer in order on a conductive substrate, especially to establish an evaluation method of an inner lead current of the photoelectric conversion device.

SOLUTION: A current value flowing in the photoelectric conversion device or quantum efficiency in a prescribed wavelength of the photoelectric conversion device is measured with a reverse bias voltage which is equivalent to at least three times as high as an open voltage of the photoelectric conversion device applied, and the photoelectric conversion device is evaluated based on the measurement values. The current value can be measured either in its bright state or in its dark state. Quantum efficiency is desirable to be compared with reference quantum efficiency measured without applying a reverse bias voltage.
