Abstract
A photovoltaic element has a first collecting electrode and a second collecting electrode on a light-receiving surface and has a configuration in which the first and the second collecting electrodes are electrically joined to each other on an insulating member. In the photovoltaic element, a second resin layer having a high compatibility with a component of the insulating member covers a boundary between the insulating member and a first resin layer formed on the light-receiving surface, thereby achieving cost reduction and improvement in durability.
Claims17
A photovoltaic element comprising a first collecting electrode and a second collecting electrode on a light-receiving surface and having a configuration such that the first and the second collecting electrodes are electrically joined to each other on an insulating member,
- wherein a first resin layer is provided on at least a portion of the light-receiving surface, and a boundary between the first resin layer and the insulating member is covered by a second resin layer having a high compatibility with a component of the insulating member, and
- wherein the first resin layer is in contact with at least a portion of the light-receiving surface and is provided on a power-generating region of the photovoltaic element.
A photovoltaic element comprising:
- a substrate having a photovoltaic layer on a light-receiving surface side thereof;
- a first collecting electrode provided on the light-receiving surface side of the substrate, for collecting electricity generated in the photovoltaic layer;
- a first resin layer coveting a light-receiving surface of the substrate;
- an insulating member provided in a portion between the photovoltaic layer and the first collecting electrode so as to be in contact with the first resin layer, for establishing electrical insulation at a portion between the photovoltaic layer and the first collecting electrode;
- and
- a second resin layer covering at least a boundary between the first resin layer and the insulating member and having a high compatibility with the insulating member.
