Not one of the figure in the article is relevant to judging the future success of this technology... Temperature delta can be increased by just putting devices in series. Cooling wattage can be increased by putting devices in parallel Cooling wattage per electrical watt with a given delta-T is the figure that matters (effectively efficiency).

Multi-stage Peltier coolers, for example, used to be absolutely horrible in yhis regard - a two stage device would need to dissipate 100W at the high temperature side to provide just 1W at the cold side. (I remember doing the math for a project around 2016, don't know how much better it is these days.)
