项目摘要

本研究の目的は①研究代表者の開発した変調光照射法を拡張して発電中太陽電池モジュール内の太陽電池セル個々の並列抵抗成分の非接触推定を実現すること、②自然太陽光下のモジュール内セル動作電圧について、観測地点上空の大気揺らぎに由来する太陽電池セルの電圧揺らぎと気象現象との相関や揺らぎを含む電圧の適正条件を把握すること、③変調光照射法によるモジュール内各セルの状態推定（セル並列抵抗成分や揺らぎを含む動作電圧）と既存手法（EL法やサーモグラフィ検査）を融合したモジュールの劣化基準を提案することである。本研究では上記①②のため、変調光照射法で周波数10kHz以上の高速変調を実現する変調器付き半導体レーザとデジタルロックインアンプを導入し、発電中モジュールへ周期変化する入射光を照射した際に変化するセル電圧のリアルタイム測定を実現し、太陽電池の国際会議PVSEC-33にて"Real-time, noncontact estimation method for voltage of one cell in generating module"として報告した。さらに①について発電中太陽電池モジュール内の測定対象セルの部分遮光により測定対象セルの並列抵抗成分を推定する方法を発展整理し、電気学会の英語論文誌にて"Partial Shading Method to Estimate the Shunt Resistance Component of a Photovoltaic Cell in a Module"として公表した。②について自然太陽光の強度揺らぎの測定システムを作製した結果、J.M. Beckers(2001)の論文との類似傾向を確認した。この自然太陽光が太陽電池モジュール内のセル個々の動作電圧に与える影響の確率モデル化を試みている。

The purpose of this study is to: (1) to conduct a study on the method of light exposure in the middle and lower reaches of the solar cell, and to list the resistance components, the non-contact presumption, the non-contact presumption, the detection of the temperature, the temperature and the temperature. The reason for the explosion above the location is that there is an accident in the battery pool, in the pool, in the battery, in the air, in the right condition, in the right condition. (3) the method of light irradiation is used to determine the status presumption of each component in the laboratory (including the action computer). The existing method (EL method) is combined with the proposal to deteriorate the standard of the system. In this study, the cycle number of solar radiation method is higher than 10kHz. In this study, the cycle number of solar radiation is higher than that of 10kHz. In this study, the cycle of solar radiation is 12 km2, the cycle number of solar radiation is higher than that of 10kHz, the cycle number of solar radiation is 12 km2, the cycle of solar radiation is 12 km2, the cycle number of solar radiation is above 12 km2, the cycle of solar radiation is 12 km2, the cycle number of solar radiation is above 12 km2, the cycle number of solar radiation is above 12 km2, the cycle number of radiation radiation method is above 12 km2, the cycle number of radiation radiation method is above 12 km2, the cycle number of radiation radiation method is above 12 km2, the cycle of radiation radiation method is higher than the cycle number of solar radiation, the cycle number of solar radiation is higher than that of high-speed radiation. Noncontact estimation method for voltage of one cell in generating module reports are not available. In the middle of the calendar, there is a partial shading test, a partial shading test, and a list of anti-constituent presumption methods, exhibition and collation, the Institute of Electronics and Electronic Science, and the "Partial Shading Method to Estimate the Shunt Resistance Component of a Photovoltaic Cell in a Module" public table. 2. The natural light intensity measurement results show that the document type of J.M. Beckers (2001) seems to confirm the error. It is natural that there is a lot of light and light in the battery. There are two operating stations in the battery. The operation of the computer and the camera make sure that it is necessary to change the operating rate of the computer.
