However, the combination placement of the light modulation film 5 and the photovoltaic cell chip 6 can construct various positional relationships, even by utilizing the low light transmittance of the photovoltaic cell chip 6, patterns, such as a luer shape, are formed by placing the photovoltaic cell chip 6.

The control module contains MPPT (maximum power point tracking), acquires maximum power by monitoring voltage and current output by the photovoltaic cell chip 6, and controls and outputs stable voltage and charges the vehicle-mounted battery through the charging and discharging circuit.
And the control module drives the charging and discharging circuit to output stable voltage to charge the vehicle-mounted battery.
