<p><P>PROBLEM TO BE SOLVED: To obtain a photovoltaic power generation system in which light-emitting elements can be replaced. <P>SOLUTION: A light-emitting unit 2 is stacked on a power generation unit 1. In the power generation unit 1, solar cells 4 are held, and an insulating plate 5 for transmitting a light is stacked on a rear plate 3 transmitting a light. The light-emitting unit 2 is provided on the insulating plate 5, and light emitting diodes 10 are provided on the rear surface of the light-emitting unit 2. Spacers 12 are interposed around the power generation unit 1 and the light-emitting unit 2. Each of the spacers 12 is made of a metal body, and its lower surface contacting the light-emitting unit 2 is bonded by an adhesive layer made from a butyl rubber or a silicon resin. The upper surface side of the spacer 12 contacts the light-emitting unit 2 via a hermetical layer having weak adhesive force to facilitate peeling of the light-emitting unit 2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
