Here are several flashing LED schematics, pay attention to the first as it can run on your 9 volts too....

i've tried all the previous diagrams that you have been sent but no one has the capacity to blink. yes, the led was lighting but no blinking. :-(

Did you do some math first or at least a Google search?
I made a joule thief that runs a LED for weeks on a single AA battery....
Making it blink is not much harder...
Question is if you can make it with a 9V battery.
They are good for things that don't really require power, so you blinking circuit must be able to provide the power for the LED from a capacitor discharge.
Blinking frequency will ffect the runtime as the battery discharges.
Also leaves the question if your panel is able to charge the battery in time.
Of course undervoltage protection is a must have too here....
