Efficiency Increasing of Single-Junction GaAs Solar Cells Coated with Species of NIR Up-Conversion Phosphors Layer on Front-Side Surface by Spin-On Film Deposition

This study demonstrates high-efficiency (23.72%) single-junction GaAs solar cell coated with species of NIR up-conversion phosphors layer on the front-side surface by spin-on-film deposition, compared to 19.36% efficiency of the reference single-junction GaAs solar cell.
