The dye‐sensitized solar cells fabricated using core‐shell upconverting nanoparticles show enhancements of ~12.5% (sensitized with black/ N749 dye) in overall power conversion efficiency under AM 1. 5G illumination. The results conclusively ascertain that the augmentation in efficiency is primarily due to near infrared to visible spectrum modification by the luminescent upconversion nanoparticles.
