Abstract:
1. A tunable photovoltaic electrochromic device at least comprising: a transparent substrate; a thin film solar cell located on the transparent substrate and at least having an anode layer, a cathode layer, and a photoelectric conversion layer between the anode layer and the cathode layer; a first transparent conductive layer located on the transparent substrate beside the thin film solar cell, wherein the first transparent conductive layer and the thin film solar cell are not mutually contacted; an electrochromic material at least covering an exposed surface of the first transparent conductive layer and the thin film solar cell; and a first switching apparatus electrically connected to the first transparent conductive layer and electrically connected to the anode layer and the cathode layer of the thin film solar cell, wherein the first switching apparatus enters a control mode through at least one switch control signal.
