My copy of the NECA national standard is old (2006) - it was updated in 2013, but the 2006 version addresses photocell controls only in section 5.0 Motorized and HVAC Equipment - Controls:

If the photocell is independent of the fixture (maybe it's controlling multiple fixtures), then the NECA standard symbol may be appropriate, but realistically it makes more sense to annotate the fixture symbol with 'PC', and define what 'PC' means within your own electrical symbol schedule:

Or, if you're publishing a fixture schedule (or specification), identify the fixture on the plan, then specify within the fixture description that it is to be controlled by a photosensor:
