Since I'm sharing solar charts here is one of solar panel efficiencies which is another of my all-time favorite charts: https://www.nrel.gov/pv/cell-efficiency.html https://www.nrel.gov/pv/cell-efficiency.html To avoid misleading, I want to clarify that the reduction in cost of solar energy has been driven far more by manufacturing scale than by efficiency improvements (although they are also relevant).
