Introduction Please explain the circuit of the solar night light! ! ! I don't know why it doesn't light up during the day but lights up at night! During the day, the solar cell turns on the 9014 on the left, then turns on the 901 on the right

Please explain the circuit of the solar night light! ! ! I don't know why it doesn't light

When it is daytime, the solar cell turns on the 9014 on the left, then turns off the 9014 on the right, then the LED light does not light up, and at the same time the solar cell charges the 3V battery. ;

At night, the solar cell The battery died, causing the left 9014 to cut out. The 3V battery only lights the right 9014 (because there is a diode, it cannot light the left 9014), then lights the LED light.
