To suppress peeling at the interface between layers due to long-term use even in a usage mode other than a flat mode.SOLUTION: A photovoltaic power generation device 100 includes a back protective layer 11, a surface protective layer 17 that is spaced apart from the back protective layer 11 and has translucency, a power generation portion 7 disposed between the back protective layer 11 and the surface protective layer 17, and a sealing layer 18 that is filled between the back protective layer 11 and the surface protective layer 17 and covers at least a portion of the power generation portion 7, and the transverse elastic modulus of the sealing layer 18 is 500 MPa or less.SELECTED DRAWING: Figure 1
【課題】フラットな態様以外の使用態様においても、長期間の使用により層間の界面で剥離が生じるのを抑制できること。【解決手段】太陽光発電装置１００は、背面保護層１１と、背面保護層１１に対して間隔をおいて設けられ、透光性を有する表面保護層１７と、背面保護層１１と表面保護層１７との間に配置された発電部７と、背面保護層１１と表面保護層１７との間に充填され、発電部７の少なくとも一部を覆う封止層１８と、を備え、封止層１８の横弾性係数が、５００ＭＰａ以下である。【選択図】図１
