HOS-PV 2.0: Exceeding the Shockley-Queisser Limit via Chiral-Induced Spin Selectivity, Dexter-Sensitized Singlet Fission, and Altermagnetic Carrier Extraction
Single-junction photovoltaic devices are fundamentally constrained by the Shockley-Queisser (SQ) thermodynamic limit (η_SQ ≈ 33.7%), primarily dictated by sub-bandgap transmission losses and the ultrafast thermalization of hot photogenerated carriers. In disordered organic photovoltaics (OPV), practical efficiency is f...
