Generation of visible photons by upconverting materials under excitation by the near-infrared part of sunlight is very attractive for complete utilization of solar energy. Visible upconversion luminescence is efficiently generated in BaCl₂:Ln³⁺ (Ho³⁺ or Pr³⁺) particles via excitation with broad band near-infrared part of sunlight. We observed greatly enhanced photocurrent response from the thin-film hydrogenated amorphous silicon solar cell covered with the upconversion layer of BaCl₂:Ho³⁺ phosphor, which demonstrates a prospective application for near-infrared photoresponse devices.
