Quantum cutting, upconversion, and temperature sensing help with thermal management in silicon-based solar cells

"photoelectric conversion efficiency 173% and enhanced heat management without changing the solar cells.... adjusting doping concentrations of Er3+ and Yb3+ in NaY(WO4)2 phosphor yields 1 material combining 3 functions: (1) quantum cutting divides short-wavelength photon into 2+ photons that join photoelectric conversion, (2) nearly pure IR upconversion combines 2+ IR photons which then join photoelectric conversion. (3) temperature sensing helps determine cooling"
