The invention provides photovoltaic dimming composite glass, and the glass comprises a first light-transmitting plate, a second light-transmitting plate, and a first bonding layer and a second bondinglayer which are positioned between the first light-transmitting plate and the second light-transmitting plate. The glass is characterized in that a dimming film is also arranged between the first bonding layer and the second bonding layer, wherein the dimming film is provided with a first leading-out wire which extends towards the edge of the glass and is led out from the edge of the glass, and the transmittance of the dimming film is changed under the driving of a power supply; a photovoltaic cell chip which is formed by connecting a plurality of independent cells in series or in parallel orin series and in parallel, wherein the photovoltaic cell chip is provided with a second leading-out wire which extends towards the edge of the glass and is led out from the edge part of the glass; the photovoltaic cell chips are arranged between the first bonding layer and the second bonding layer side by side, and the distance between the edges of the photovoltaic cell chips and the edge of thedimming film is greater than or equal to 5 mm. Daylighting and photovoltaic power generation are both considered, electricity generated by photovoltaic power generation can be directly supplied to thedimming film for use, the appearance is neat, the overall structure is simple, and implementation is easy.
