the photovoltaic cell chips 6 are arranged between the first bonding layer 2 and the second bonding layer 3 side by side, and the edge distance between the edges of the photovoltaic cell chips 6 and the edge distance between the light adjusting films 5 is larger than or equal to 5 mm. Set up photovoltaic cell chip 6 at least on one side of membrane 5 of adjusting luminance, photovoltaic cell chip 6 and membrane 5 of adjusting luminance are on the same layer, and the mid portion of whole glass is membrane 5 of adjusting luminance, and 5 sides of membrane of adjusting luminance are photovoltaic cell chip 6. It can be understood that the photovoltaic cell chip 6 is a part with lower light transmittance, and the light adjusting film 5 has a transmission state with high transmittance, and the light adjusting film 5 is arranged in the middle, and the photovoltaic cell chip 6 is arranged on the side edge, so that the lighting performance of the automobile glass can be guaranteed to the maximum. However, the combination and placement of the light modulation film 5 and the photovoltaic cell chips 6 can construct various positional relationships, and even the low light transmittance of the photovoltaic cell chips 6 is utilized to form patterns, such as "lu" shapes, by placing the photovoltaic cell chips 6.
The first light-transmitting plate 1 and the second light-transmitting plate 4 can be made of tempered or common inorganic glass or organic glass, the first light-transmitting plate 1 and the second light-transmitting plate 4 can also be made of laminated glass to improve the overall safety of the glass, the first light-transmitting plate 1 and the second light-transmitting plate 4 can be made of curved glass, curved functional laminated glass suitable for automobiles can be obtained in the occasion of using the curved glass, and other laminated layers between the first light-transmitting plate 1 and the second light-transmitting plate 4 are curved surfaces with corresponding curvatures.
The dimming film 5 is a component capable of electrically controlling dimming, and is one of a PDLC component, an EC component, and an SPD component, which are common dimming technologies in the art. Preferably a PDLC module, typically consists of two transparent substrate layers coated with a transparent conductive layer ITO, with a polymer dispersed liquid crystal material sandwiched therebetween. When the PDLC component is used, the following 2 effects can be achieved: when the scene outside the window is to be seen, the PDLC is adjusted to be in a bright state; when the privacy in the vehicle is to be protected, the PDLC is regulated to be in a dark state. In the two PDLC states, the light scattering part of the PDLC forms an optical waveguide in the ITO layer, and the part of light is transmitted and then incident on the photovoltaic cell chips 6, so that the absorption of some photovoltaic cell chips 6 on light can be increased, and the electrical property output of the photovoltaic cell chips 6 can be improved to a certain extent.

sensor circuitry, which collects environmental parameters and converts them to signals, includes temperature sensors, light sensors (not shown). The temperature sensor carries out effective temperature compensation on the vehicle-mounted battery, and when the working temperature of the battery is higher than a normal value, the control module automatically cuts off the charging circuit to reduce the temperature of the battery. When the temperature is reduced to a normal value, the control system starts the charging circuit to recover the charging function. When the photovoltaic is not output at night, the control module automatically cuts off the charging circuit after receiving the signal transmitted by the illumination sensor; when the lamp shines in the daytime, the control module automatically starts the charging circuit.
The control module receives the signal transmitted by the sensor circuit, sends an instruction according to the signal, tracks the voltage and the current of the photovoltaic output, and enables the photovoltaic output to be kept at the maximum value to charge the vehicle-mounted battery through the collected voltage and current; when the dimming switch is turned on, the control module starts the inverter circuit, and direct current output by the vehicle-mounted battery or the photovoltaic-dimming composite glass is converted into alternating current to supply power to the dimming film for working. The control module contains MPPT (maximum power point tracking), obtains the maximum power by monitoring the voltage and the current output by the photovoltaic cell chip 6, and controls to output stable voltage and charge the vehicle-mounted battery through the charging and discharging circuit.
And the control module drives the charge-discharge circuit to output stable voltage to charge the vehicle-mounted battery.
