The limitation efficiency of single-junction
solar cells can theoretically be overcome byembedding quantum dot (QD) layers within
the absorber material. However, a single QD
layer absorbs only a small fraction of theincident light. In this work, we explain theinterest of optimizing the position of QD
layers to increase absorption and validate it
experimentally with Fabry-Perot resonances.

Many researches have been reported oncontrolling the scattering of light using Mie

crystalline-Silicon (c-Si) Mie resonators canbe applied to structural color images withdiffraction limit resolution. We aim to extend
such structural colors to near infrared (IR)region. In this study, we demonstrate“concealed images” at near-IR by c-Si Mie
resonators, which cannot be seen in visible
