A DEVICE HAVING AN ELECTRICALLY CONTROLLABLE OPTICAL PROPERTY

摘要

The present disclosure provides a device having an electrically controllable optical property. The device comprises a panel that is at least partially transmissive for visible light. The panel has a receiving surface for receiving incident light and is arranged such that a portion of the incident light is redirected towards regions that are at edges or side portions of the panel. Further, the device comprises at least one photovoltaic element for generating electricity, the at least one photovoltaic element being arranged at the side portion or edge of the device. The device also comprises a control layer that has an electrically controllable optical property for controlling an optical property of the device. The device is arranged such that at least a portion of the incident light is redirected towards the at least one photovoltaic element to generate electricity and at least a portion of the generated electricity can be provided for the control layer.
