Capacitance in AC Circuits and Capacitive Reactance
At 0 o the rate of change of the supply voltage is increasing in a positive direction resulting in a maximum charging current at that instant in time. As the applied voltage reaches its maximum peak value at 90 o for a very brief instant in time the supply voltage is neither increasing or decreasing so there is no current flowing through the circuit.

As the sine wave starts to fall, the diode is not turned on any more, so the capacitor that was fully charged startra releasing the charge to a load, so voltage drops slowly.
