Your numbers are outdated. Thin film = 23%, multi-junction are 46%. "Standard PV" is probably what's available in bulk and cheap, is around 22-25%. https://up

  Those are best in class research cell efficiency for each technology type. The silicon cell based panels you can buy now are 17.5-22% unless you are spending a lot of money. Special thin films cells in a lab may be 23%, what you can buy economically for a grid scale utility power plant is more like 14-15%. This is at the very top end of the thin film market for what is now commercially available, and is 17%.
