Embodiments of the fourth aspect of the present application also provide an electrochromic photovoltaic window 02, the electrochromic photovoltaic window 02 comprising at least the electrochromic photovoltaic assembly 03 of any of the aspects of the first aspect. In some embodiments, comprising an electrochromic photovoltaic module 03 of any one of the claims; and tempered glass 04 connected with the electrochromic photovoltaic module 03; and a connection structure 01 for connecting the electrochromic photovoltaic module 03 or the toughened glass 04 or the building 05. The connection structure also carries the energizing structure of the electrochromic photovoltaic module 03. In other embodiments, electrochromic photovoltaic window 02 comprises: electrochromic photovoltaic module 03; the energizing structure of any of the claims; tempered glass 04 connected with the electrochromic photovoltaic module 03; and a connection structure 01 for connecting the electrochromic photovoltaic module 03 or the toughened glass 04 or the building 05.

In some embodiments, the number of the electrochromic photovoltaic modules 03 and the number of the tempered glass 04 are one; wherein, the electrochromic photovoltaic module 03 is connected to the building 05 above through the connection structure 01, and the electrochromic photovoltaic module 03 is connected to the toughened glass 04 below through the connection structure 01.

In some embodiments, the electrochromic photovoltaic module 03 and the toughened glass 04 are all multiple in number; wherein, each electrochromic photovoltaic module 03 is connected to the building 05 above through the connection structure 01, and each electrochromic photovoltaic module 03 is connected to one toughened glass 04 below through the connection structure 01.

In some embodiments, the number of electrochromic photovoltaic modules 03 is one, and the number of tempered glass 04 is a plurality; the electrochromic photovoltaic module 03 and the toughened glass 04 adjacent to two sides of the electrochromic photovoltaic module 03 are connected to the building 05 above through the connecting structure 01, and the electrochromic photovoltaic module 03 and the toughened glass 04 adjacent to two sides of the electrochromic photovoltaic module 03 are connected to one toughened glass 04 below through the connecting structure 01.

In this application, the change in electrochromic layer 035 changes the color, transmittance, absorbance and/or reflectance of electrochromic photovoltaic window 02, darkening or brightening electronically. For example, a small voltage applied to electrochromic layer 035 may darken electrochromic photovoltaic window 02 and a large voltage applied to electrochromic layer 035 may lighten electrochromic photovoltaic window 02. This allows controlling the amount of light passing through the electrochromic photovoltaic window 02 for the purpose of regulating the indoor environment. The light transmittance of the electrochromic photovoltaic module 03 and the electrochromic photovoltaic window 02 is changed along with the change of outdoor illumination, for example, when outdoor light is strong, the power generation efficiency of the electrochromic photovoltaic module 03 is high (the output power is improved), and the light transmittance of the electrochromic photovoltaic module 03 is reduced (the transmittance is changed from transparent to semitransparent) by leading the first voltage to the electrochromic layer 035; for example, when outdoor light is reduced, the power generation efficiency of the electrochromic photovoltaic module 03 decreases (the output power decreases), and by passing the electrochromic layer 035 to less than the second voltage, for example, the first voltage is less than the second voltage, the transmittance (from translucent to transparent) of the electrochromic photovoltaic module 03 is increased.

In the application, through the combined arrangement of the building 05 and the electrochromic photovoltaic module 03 or/and the toughened glass 04, electrochromic photovoltaic windows 02 which convert solar energy into electric energy in different forms can be formed. The connection structure 01 is widely applied between the electrochromic photovoltaic module 03 and the toughened glass 04, between the electrochromic photovoltaic module 03 and the building 05 (such as a wall or a window frame), and between the toughened glass 04 and the building 05. The connecting structure 01 has strong clamping force and improves the waterproof effect of the electrochromic photovoltaic module 03.
