Abstract:
1. A solar panel, comprising: a covering-glass substrate having a first surface, a second surface, and a side surface extending between the first and second surface, the second surface having a periphery section and a solar cell layer section, the periphery section surrounding the solar cell layer section, the periphery section having a smaller thickness than the thickness of the solar cell layer section in a cross sectional view, the periphery section including a first portion and a second portion, at the periphery section the solar cell layer being reliably removed to ensure exposing a face of the covering-glass, the second portion surrounding the first portion, the first surface being directed to the sun, the second surface being subjected to have layers and films thereon; a solar cell layer including a plurality of films formed on the solar cell layer section of the second surface, the films including, in order from the substrate, a transparent electrode film, at least a semiconductor film, and a metal film; an adhering sheet on the first portion of the periphery section of the second surface, the adhering sheet covering the edges of the films and the surface of the metal film and being smaller than the covering glass substrate in a direction in which the first surface and the second surface extend in the cross sectional view perpendicular to the first surface and the second surface; a covering sheet on the adhering sheet, the covering sheet being in contact with the adhering sheet at the periphery thereof and being smaller than the covering glass substrate in a direction in which the first surface and the second surface extend in the cross sectional view perpendicular to the first surface and the second surface; and a sealing material sealing the second portion of the periphery section of the second surface and the peripheries of the adhering sheet and the covering sheet so as not to cover the first surface of the glass substrate, wherein the sealing material contacts a portion of each of the adhering sheet, the covering sheet, and the second surface of the substrate, surrounds the adhering sheet and the covering sheet, and does not contact the substrate except the second surface thereof, wherein no sealing material is present on the first surface of the glass substrate and side surface of the substrate.
