Abstract

The invention provides a tunable solar photovoltaic electrochromic assembly and module. The assembly comprises a transparent substrate, a thin-film solar cell positioned on the transparent substrate, transparent conductive layers positioned on the transparent substrate beside the thin-film solar cell, an electrochromic material covering exposed surfaces of the transparent conductive layers and the thin-film solar cell, a switching device, and a charge-discharge device coupled to the switching device. The first transparent conductive layer and a cathode layer of the thin-film solar cell respectively serve as an anode and a cathode of the electrochromic material simultaneously. The switching device is electrically connected to a first transparent conductive layer and electrically connected to an anode layer and a cathode layer of the thin-film solar cell, and enters a control mode through a switch control signal.

Description

technical field [0001] The present invention relates to an electrochromic component, and in particular to a tunable photovoltaic electrochromic component (tunable photovoltaic electrochromic device) and a module. Background technique [0002] Typical structures of electrochromic components are divided into solid-state type and solution type. The structure of solid-state electrochromic components is composed of upper and lower transparent substrates and multi-layer coatings / plating layers with different functions in between (such as transparent conductive layers, electrochromic films, solid electrolytes and ion storage layers). structure. The structure of the solution-type electrochromic component is composed of two conductive transparent substrates, a transparent conductive electrochromic coating and an electrolyte solution between the substrates. [0003] Compared with electrochromism, which has a long history, photoelectrochromism technology can make the electrochromic l...
