Two-faced solar panels can generate more power at up to 70% less cost

I briefly pondered this same idea when first hearing about how cats have such good night vision (they have basically got a mirror _behind_ their light receptors which increases the chance of a stray photon getting picked up)
Not quite the same thing I'm sure...
I just saw article about this study; "Methodology for the estimation of cultivable space in photovoltaic installations with dual-axis trackers for their reconversion to agrivoltaic plants" (2024) https://www.sciencedirect.com/science/article/pii/S030626192... https://www.pv-magazine-india.com/2024/03/19/how-to-convert-...
Albedo: https://en.wikipedia.org/wiki/Albedo :
> Surface albedo is defined as the ratio of radiosity J_e to the irradiance E_e (flux per unit area) received by a surface. [2]
IDK what a reasonable adjustment factor for dual-sided single-junction cells given crop albedo would be
Technically, even with one-sided panels, it's probably actually necessary to also model light that bounces off a shiny crop back into the air above the panel and diffuses and reflects against other radiation and scatters back to the panel; it's probably necessary to model albedo (or reflectivity) for single-junction cells too.
Why not multi-junction cells?
