BLINDS AND PHOTOVOLTAIC DEVICE

摘要

Blinds of one embodiment of the present invention which are provided with a plurality of blocking parts that can block light, wherein the blocking parts have photovoltaic devices that convert the energy of light into electricityand the photovoltaic devices include a first photovoltaic part and a second photovoltaic part one of which is positioned on a side toward the inside of a room and the other positioned on a side toward the outside of the room. Of the first photovoltaic part and second photovoltaic part, the electrical connection of the photovoltaic part for which a voltage measured by a voltage measurement part is a prescribed voltage or less is disconnected.
