Bifaciality isn’t new or limited to perovskite based PV. Ground reflection is also not the only source of indirect light.
This article is very bad, but bifacial panels are starting to dominate the industry for good reason. The backside gives a 5-20% boost in total annual yield (which is worth it on its own), but more importantly that boost is skewed towards times with low direct irradiance (such as cloudy days). This reduces the amount of storage required.
It also allows other orientations. Vertical installations have huge advantages including better compatibility with agrivoltaics, generation skewed towards times where flat panels don’t produce, better dual use, and lower racking cost.

Thanks for the background. My panels are dual glass encapsulated but not bifacial – not that I would be able to profit from it anyway.
