Delta energy required to excite hole from lowest energy orbit to valence band?

I have calculated the orbit of a hole in its lowest energy orbit, but am struggling to work out \delta\epsilon (energy needed to excite it to valence band).

Any help much appreciated.

"the orbit of a hole in its lowest energy orbit"

what do you mean by that?

1) Holes are just a conceptual construct that help us do the math easier. Holes do not exist.

2) What do you mean by the orbits?
