The cell includes an electrode substrate, a counter substrate, an oxide semiconductor layer provided on the electrode substrate, an electrolyte provided between the electrode substrate and the counter substrate, and an annular sealing portion joining the electrode substrate and the counter substrate. The layer includes a main body portion provided inside the sealing portion and on the electrode substrate and extending straight from the electrode substrate toward the counter substrate, and a protruding portion which protrudes from the main body portion toward the sealing portion and does not come into contact with the electrode substrate. A width of a second surface of the layer facing the counter substrate is longer than a width of a first surface which is a boundary surface between the layer and the electrode substrate in a cross section along a thickness direction of the layer.

In various embodiments, photovoltaic modules are hermetically sealed by providing a first glass sheet, a photovoltaic device disposed on the first glass sheet, and a second glass sheet, a gap being defined between the first and second glass sheets, disposing a glass powder within the gap, and heating the powder to seal the glass sheets.

A photovoltaic device comprising a first electrode, a second electrode, an active layer disposed at least partially between the first and second electrodes, an interfacial layer disposed at least partially between the first and second electrodes, and a non-stoichiometric oxide layer disposed at least partially between and in contact with one of the first or second electrodes and an encapsulant layer. The active layer of the photovoltaic device comprises a photoactive material.

A photoelectric conversion device includes: a photoelectric conversion cell including an electrode substrate; a counter substrate facing the electrode substrate; a seal that is ring-shaped and that joins the electrode substrate and the counter substrate; and an antenna coil disposed on a side of the electrode substrate opposite to the counter substrate. The antenna coil overlaps with the seal when the seal and the antenna coil are viewed in a thickness direction of the seal.
