A photovoltaic device including a photovoltaic module disposed on or above an insulating substrate , which is provided with holes for receiving conducting paste terminals of the module formed on the substrate . A plurality of conducting materials are connected electrically with the conducting paste terminals , and a protective resin film is provided to protect the terminals. The protective resin film has openings at positions corresponding to the conducting materials , and the openings are larger than the topside shape of the conducting materials . The conducting materials are disposed inside of the openings.

Photovoltaic device and a method of manufacturing thereof

The photovoltaic device is provided with a photovoltaic element on the surface of a substrate, and a light diffuse transmission filter, which diffuses light passing through it, over the surface of the photovoltaic element. The light diffuse transmission filter is separated from the surface of the photovoltaic element via spacers or via a light transmitting gap layer.

Photovoltaic device

A display device has a front panel including a solar battery on its surface. At least one window is formed in the solar battery to permit viewing a character formed in the front panel. Energy produced by the solar battery is stored in a storage battery for illuminating light emitting devices situated behind the front panel. The illumination provides background lighting for characters in the window of the front panel. Another embodiment of the invention uses a solar battery with an illuminated layer behind the front panel on which characters are displayed by either removing unwanted segments of a pre-formed character on the front panel or by adding segments of the characters with masking material.

A method of forming a lead-out electrode in an integrated-type photovoltaic device including photoelectric conversion cells connected to each other in series on a transparent substrate is to form a lead-out electrode portion or section by separating a laminate of a semiconductor photo-active layer and a back electrode layer into back electrode and lead-out portions by means of a scanned laser beam. The major part of the lead-out electrode portion is elongated and has, at the opposite end, enlarged sections for receiving external lead wires or conductors. Accordingly, the lead-out electrode portion occupies only a small area in the substrate and can be formed easily by scanning with a laser beam.
