| Outline of Final Research Achievements |
To evaluate the electrical current distribution inside a cell, magnetic measurement system which can detect a magnetic field distribution generated from an electrical current was developed. Using the developed system, the electrical current distribution of a dye sensitized solar cell was measured and the correlation between the electrical current distribution and the electrical characteristics of solar cells were investigated.
As a result, the electrical current distribution inside one solar cell was almost uniform in spite of the dye and catalysis material of solar cell. However, the electrical current distribution changed when the electrical property of solar cell showed a low performance.
Moreover, a new evaluation method of AC impedance using magnetic measurement was demonstrated which can analyze internal structure of solar cell. This result suggests the analysis of AC impedance at localized region which is difficult using a conventional AC impedance measurement system.
