In the past, I've heard that it may possibly be a charged electron, but that sounds a bit wrong...but in a universe of infinitely finite possibilities we can only assume. I know that momentum does have a big role on how solar sails work, but is there anything more in depth?

Oh I forgot, kids can't use wikipedia for school work. Sorry, OP.
Not anything related to school, just wanting to know how photons really work within a solar sail and 'light' system. Wiki isn't the best place for information.
Photons do have mass
They have an acceleration
They can exert a (very small) force

Photons have momentum. Zero rest mass but relativistic mass/energy equivalence.
Photons going towards a sail have opposite momentum to photons going away from the sail.
Conservation of momentum happens at the sail.
