Seems like quite a few of these could be avoided by regular maintenance.

  No, the biggest killer of PV cells is natural degradation Photons and other energetic particles knock Silicon atoms out of lattice, and tear the junction layer. There is no 100% efficient trick against that so far in any common semiconductor. Lithium dopant was once used in space PV cells. It almost halves the decay rate, but even that was not considered enough to warrant using it over simply having bigger area of less durable, but more efficient cells.
