Theoretical maximum solar radiation
Webb1 okt. 2024 · Single-junction solar cells have a maximum theoretical efficiency of 33.16%, the Shockley-Queisser limit. But there are work-arounds that permit solar array designers to surpass that limit on a square-foot basis. The maximum solar conversion efficiency of around 33.7% happens at a 1.34 eV band gap and is subject to several assumptions. WebbWhat is the theoretical maximum efficiency of conversion if bluelight of wavelength 0.45 μm is incident on a GaAs solar cell?
