A photovoltaic module includes a front protective layer, a back protective layer, a plurality of solar cells, and a filler. The front protective layer is transmissive to light and has a first surface and a second surface opposite to the first surface. The back protective layer faces the second surface. The plurality of solar cells are between the second surface and the back protective layer. The filler is between the front protective layer and the plurality of solar cells and covers the plurality of solar cells. The filler includes a material with a chemical structure to generate a free acid. The front protective layer includes a weather-resistance resin. At least a part of the first surface is exposed to a space external to the photovoltaic module.

An insulation paste for forming a protective layer of a solar cell device includes: a siloxane resin; an organic solvent; and multiple fillers each having a surface covered with an organic coating containing at least one material different from a material of the siloxane resin. A method for producing the insulation paste includes: preparing the multiple fillers; and mixing together a precursor of the siloxane resin, water, a catalyst, an organic solvent, and the multiple fillers. A method for manufacturing a solar cell device includes: applying the insulation paste to the passivation layer; and drying the insulation paste to form the protective layer on the passivation layer. A solar cell device includes: the passivation layer located on a semiconductor region; and the protective layer located on the passivation layer and including a siloxane resin and dimethylpolysiloxane.
