<p><P>PROBLEM TO BE SOLVED: To provide a mounting surface area for mounting solar cells by utilizing a rolling curtain installed at a window of a building. <P>SOLUTION: In a rolling curtain 1, a film solar cell 6 is mounted on a surface facing to a window of a rolling screen body 3a, and the film solar cell 6 is connected as an electric source to a storage battery 8 and a load 4 though a charge-discharge controller 7. As a result, a mounting area of the film solar cell 6 is effectively provided without any adverse effect on function of the curtain, and the workability becomes good. By including an electric storage battery, it can be used as a backup electric source when necessary, or as an emergency power supply if necessary in case of a disaster. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
