A half wave rectifier does cut half the voltage off and a full wave rectifier inverts it. But an 81v peak to peak AC voltage cut in half is still over 40 volts ripple DC. The diodes in a rectifier bridge eats .7 volts per diode...4 diodes = -2.8v...37.2 volts. Even out the ripple some with capacitors and chop off the top with a 30v zener to get true DC and I get 30v DC out of a 100ma 24v AC to AC transformer. Apply a load and the voltage drops too, but CS generators pull very little current.
Wall warts [and batteries] are rated to give the labeled voltage at the labeled current. Actual voltage is higher. A 12 volt car battery is usually 13.5 volts and goes down to 8 volts when the starter is running. Your average 12 v solar cell runs at 18v with no load.
