There have been lots of news items like this over about the last 15 years, from memory, often talking about UNSW solar developments/breakthroughs which are going to lead to cheap PV panels but it never really seems to happen. $/W, panels haven't reduced in cost all that much over the years, until the cheap Chinese imports started arriving on ebay.
I wonder if the new PV cells really are >60% efficient in converting sunlight into electricity, or they are including the hot water heating power in the 4X better calculation?
60% efficient panels would start to make lightweight solar powered cars look more feasible
