The polymer solar cell is able to retain 97% of its performance after 2,000 hours in air. By blending small-molecule acceptors into polymeric matrices, the research team improved molecular packing, enhancing both stability and charge transport for "ultra-stable" flexible devices.
Title suggests that coming down an order of magnitude is somehow a minimum bar that has to be crossed, but that’s nonsense, no one does that. In the same time span as in the graph linked above, how much do you think the cost of fossil fuels has gone down since 1975?
Title is incorrect, solar has decreased more than an order of magnitude in cost. In fact it’s gone down by more than TWO orders of magnitude. - https://ourworldindata.org/data-insights/solar-panel-prices-have-fallen-by-around-20-every-time-global-capacity-doubled

I think they mean that solar is poised for a reduction in cost.
