Rare‐Earth Ion Doped Up‐Conversion Materials for Photovoltaic Applications

With the aim of utilizing the infrared region of solar radiation to improve solar cell performance, significant progress, including theoretical analysis and experimental achievement, has been made in the field of up‐conversion for photovoltaic applications. This Research News article reviews recent progress in the development of rear‐earth (RE) ion doped up‐conversion materials for solar cell applications. In addition, new trends for RE‐ion‐doped phosphors are briefly discussed, among them trivalent RE‐ion‐doped up‐conversion materials for organic solar cell applications.
