This paper describes the measurement of an organic photovoltaic using an electro-optic probe. We verify the validity of the electro-optic probe by comparing it with a conventional electric probe. The electric field distribution of the organic photovoltaic is examined on the basis of results of the test board measurement using the electro-optic probe and results of the test board simulation using an electromagnetic field simulator. We succeed in failure diagnosis of the organic photovoltaic in three failure modes. We found that the organic photovoltaic has a failure cell, and the electro-optic probe is successfully applied to failure diagnosis of organic photovoltaic.

Key words: electro-optic probe, organic photovoltaic, failure diagnosis, electric field distribution, electromagnetic field simulation
