摘要

Printable photovoltaic electrochromic device comprises: a transparent substrate (100); at least one thin-film solar cell (102), which is arranged on a transparent substrate, where the thin-film solar cell comprises an anode layer (106), a cathode layer (108) and a photoelectric conversion layer between the anode layer and cathode layer, and a portion of the anode layer or a portion of the cathode layer is exposed from the thin-film solar cell; and at least one single polarity electrochromic thin film (104), covering and contacting with both the cathode layer and the anode layer.
