Adding Circuit Breakers

I have a GE Breaker Panel TM4020C. All the breaker slots have been used and I now have need to add addition circuits. This panel uses 1" breakers and the GE type QP breaker which is 1/2" will not work in this panel. Is there a 1/2 (piggy back) breaker that fits this panel? If not is there another solution?

Thanks

Looking at your catalog number I want to say it is a 20 space, 40 circuit panel. Can you see what breakers are approved for this panel on the label? Do you see THQP anywhere?

GE doesn't make a tandem breaker, but uses the type THQP thin breakers instead.
