There was a report from MIT a few years back that looked into the price reductions of solar between 1978 and 2012, during which time module costs fell by 97%.
They suggest that early on R&D support from government was key, then later market support to help grow the scale of deployment. Since 2001 its been manufacturing scale that has dominated price reductions.
