Zusammenfassung:	To suppress deterioration of power generation characteristics by a PID that is predicted to be generated when Na contained in a cover glass or the like of a solar cell module moves inside the cell due to a voltage applied to a system, and in which the power generation characteristics are significantly reduced in a short period of time compared with other deterioration modes.SOLUTION: In a solar cell module, a high-resistance glass layer is formed on at least one surface of a surface-side transparent protective member made of a glass substrate or the like on the side where sunlight is introduced.SELECTED DRAWING: Figure 2 【課題】ＰＩＤは、太陽電池モジュールのカバーガラス等に含まれるＮａがシステムに印加された電圧によりセル内部に移動して発生すると予測されており、他の劣化モードと比較して、短期間かつ大幅に発電特性が低下する。本発明は、ＰＩＤによる発電特性の低下を抑えることを目的とするものである。【解決手段】太陽光の導入側にあるガラス基板などからなる表面側透明保護部材の少なくとも一方の表面に、高抵抗ガラス層を形成したことを特徴とする、太陽電池モジュール。【選択図】図２
