You may get better replies if you post a short file that can be
fed to Lilypond as is, with \time, \clef etc.

I suggest that you use \voiceOne and \voiceTwo instead of \stemUp and
\stemDown.  Voice styles control more than stem direction and they take
care of some stem collisions.

Normally the easiest approach would be to increase distance between
staves:

\new PianoStaff \with {
  \override StaffGrouper #'staff-staff-spacing #'minimum-distance = #12
} <<
