If your "9V" battery is actually a 7.2V or 8.4V Ni-Cad or Ni-MH type then a complicated charger circuit is needed. Solar panels are made to charge 12V batteries, not 18V batteries. I have never heard of an 18V battery nor a solar panel rated at 18V but most 12V panels produce 18V with no load current.
decided to build a solar charger for his car battery. He had an 18V solar panel able to provide up to 83mA. You cannot connect the panel directly to the battery because charging voltage cannot exceed the allowed safe limit, and also solar panels may become a load for the battery in a dark time, and this way discharge it. So he ended up with a simple circuit utilizing

Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
But to charge a battery with a solar panel, the most popular choice is the MPPT or maximum power point tracker topology because it provides much better accuracy than other methods like PWM controlled chargers. MPPT is an algorithm commonly used in solar chargers.
In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell. Because there is a D1 blocking it, the current can flow only one way. The energy in the battery is stored and gradually increases until it is full.
