Abstract
- In this work, granular Y 2 O 3 /Y 3 Al 5 O 12 (YAG) heterostructure thin films with 100–200 nm holes on surface were fabricated by depositing metal yttrium on c-plane sapphire and subsequent thermal anneal. Such Y 2 O 3 /YAG thin films are excellent matrix for luminescent materials based on rare earth. Based on this matrix, a Cr 3 + /(Pr 3 + /Yb 3 + ) broadband down-converter was fabricated for improving the photovoltaic conversion efficiency of crystalline silicon solar cell (c-Si SC). Cr 3 + was used to harvest the incident light and sensitize Pr 3 + /Yb 3 + quantum cutting (QC) couple. QC down-conversion to Yb 3 + infrared emission was realized in the region of 230 nm to 500 nm, which approaches the maximum bandwidth of QC down-conversion for c-Si SC. [ABSTRACT FROM AUTHOR]
