I don't understand your objection. The title of the press release is "Scientists Design Solar Cell That Captures Nearly All Energy of Solar Spectrum". That title is not "Scientists develop new multijunction cell", but instead implies they've designed something novel. First paragraph: "Scientists have designed and constructed a prototype for a new solar cell that integrates multiple cells stacked into a single device capable of capturing nearly all of the energy in the solar spectrum. The new design converts direct sunlight to electricity with 44.5 percent efficiency, giving it the potential to become the most efficient solar cell in the world." That describes a multijunction cell, without mentioning that the idea is decades old. They describe an efficiency of 44.5%, without mentioning that other multijunction cells beat that efficiency years ago. I think you need to reread the article. Mentioning multijunction cells in the fourth paragraph is not a sufficient description of prior art.
