They contain a diode for charging the single NiMh cell from the solar panel, but also use the voltage from the solar panel to detect when it's dark enough to turn the light on. The circuit pulses a small inductor at about 100kHz to step up the voltage to drive the LED in a similar style to a Joule Thief circuit.

Simple Solar Circuits | Evil Mad Scientist Laboratories

A solar garden light circuit. While the last circuit works well for driving a yellow or red LED, it runs at 2.4 V (the output of the NiMH battery), it does not have sufficient voltage to drive a blue or white output LED. So, we can add to that circuit the simple Joule Thief voltage booster to get a good design for a solar garden light: A solar-charged battery with a dark detector that drives a Joule Thief to run a white output LED.
