Abstract

A photoelectric conversion element includes a cell which includes a pair of substrates, an oxide semiconductor layer provided on one of the substrates, an electrolyte provided between the substrates, and a sealing portion joining the substrates. At least one of the substrates includes a joining portion joined to the sealing portion and a non-joining portion present inside the joining portion and not joined to the sealing portion. The joining portion includes first linear portions spaced apart from each other, and a first connecting portion connecting two first linear portions among the first linear portions. Additionally, the first connecting portion is formed by cutting off a whole corner portion on an opposite side from the non-joining portion in a first intersecting portion formed by extending and crossing the two first linear portions along a thickness direction of the substrates when the substrates are viewed in the thickness direction thereof.

Dependent claims

A photoelectric conversion element comprising:

a photoelectric conversion cell comprising a pair of substrates;
an oxide semiconductor layer provided on one of the pair of substrates;
an electrolyte provided between the pair of substrates;
and
an annular sealing portion that joins the pair of substrates together,
wherein at least one of the pair of substrates includes an annular joining portion joined to the sealing portion and a non-joining portion located inside the joining portion and detached from the sealing portion, and
wherein the joining portion includes:
a plurality of first linear portions spaced apart from each other, and
a first connecting portion that connects two first linear portions among the plurality of first linear portions, and
wherein the first connecting portion is formed by cutting off a corner portion on an opposite side from the non-joining portion in a first intersecting portion formed by extending and crossing the two first linear portions along a thickness direction of the substrates when the substrates are viewed in the thickness direction thereof.
