That should trigger the circuit and turn on the device. If it''s the other way around (resistance increases with light) just solder a wire where the photocell used to be. The problem is that it will run until the battery runs out of juice, and won''t start again until the solar cell charges it up enough, but this seemed like the simplest solution.

A solar panel typically charges a battery that powers an LED light. A charge controller ensures the solar panel properly charges the battery, and a DC-DC LED driver circuit connects the battery to the light. An ambient light sensor alerts the system when it''s dark enough to turn the light on, and to turn it back off again as the sun comes up.
When the switch is in the ON position, the light will charge during the day and turn on at night. When the switch is in the OFF position, the light will still charge but won''t turn on at night. OL4 without ON/OFF Switch: The solar warning light without an ON/OFF switch is preprogrammed to turn on at night. Simply mount the light where you ...

Here is a simple Solar Night lamp that turns on automatically at sunset and stays on till morning. It uses 1 Watt High Bright White LEDs to illuminate a confined area.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
The solar cells are wired directly to the battery through a diode (which prevents the battery''s current from flowing back through the solar cell at night). The battery is a completely standard AA Nicad battery. A battery like this produces about 1.2 volts and can store a maximum of approximately 700 milliamp-hours.
