PHOTOVOLTAIC ELECTROCHROMIC DEVICE
First Claim
1. A photovoltaic electrochromic device, comprising:
- a transparent non-conductive substrate;
a semi-transparent thin-film solar cell substrate, comprising a transparent substrate and a plurality of thin-film solar cells, wherein an anode and a cathode of each of the thin-film solar cells also serve as an anode and a cathode of the photovoltaic electrochromic device; and
an electrochromic solution disposed between the transparent non-conductive substrate and the semi-transparent thin-film solar cell substrate.

Abstract
A photovoltaic electrochromic device includes a semi-transparent thin-film solar cell substrate, an electrochromic solution, and a transparent non-conductive substrate, wherein the electrochromic solution is located between the transparent non-conductive substrate and the semi-transparent thin-film solar cell substrate. The semi-transparent thin-film solar cell substrate includes a transparent substrate and a plurality of thin-film solar cells, wherein the anodes and the cathodes of the thin-film solar cells are also used as the anodes and the cathodes of the photovoltaic electrochromic device. Because a driving voltage of the electrochromic solution is low, the thickness of an intrinsic layer in each of the thin-film solar cells can be thinned, which increases the transmittance of the photovoltaic electrochromic device. Besides, the current output of the photovoltaic electrochromic device can be controlled by an additional output switch layout coupled with the thin-film solar cells.
