PURPOSE:To obtain a photovoltaic device with high shock resistance, by forming a multiplicity of photoelectric conversion films which define photovoltaic elements on the surface of a large light-trasmitting substrate, cutting the films into groups each including a desired number of elements, and securing a light-receiving plate of tempered glass to the reverse surface of the substrate. CONSTITUTION:A multiplicity of photoelectric conversion film 3 are formed on the surface 1S1 of a large substrate 1a made of light-transmitting and insulative glass, ceramic or the like, each film 3 being a laminated structure 7 consisting of a light-transmitting electrically conductive oxide film electrode 4 such as tin oxide, an amorphous Si photoactive layer 5 and an Al ohmic electrode 6. The films 3 are divided into groups each including a desired number of films 3 which are connected together by connecting electrodes 9 through adjacent spacing areas 8. The reverse surface 1S2 of the substrate 1a is coated with a bonding layer 11, and a light-receiving plate 10 of tempered glass is bonded to the reverse surface 1S2, the bonding layer 11 having a reflative index substantially equal to that of the light-receiving plate 10. Thereafter, the film 3 connected in series are cut for each group, thus obtaining a photovoltaic device having an increased mechanical strength. |
