Abstract

Ultrathin-thickness single-junction Si-based solar cells can be developed to enhance photoelectric conversion efficiency (PECE) approaching to Shockley–Queisser limit. However, loss of short circuit current is a crucial factor that dramatically affects PECE improvement. Even though many studies have focused on rare reflector architecture for facilitating near-infrared radiation absorption, PECE is still constraint due to its fabrication cost. Herein, an upconversion sustainable micro-optical trapping device is reported. Using a systematic procedure, a high upconversion performance core–shell-nanoparticles (CSNPs) structure is synthesized. Accordingly, silica diatom microporous frustule is a good electromagnetic field localization chamber, upon which CSNPs are embedded through a microassemble synthesis. This emerging device can be support on ultrathin-thickness single-junction Si-based solar cells as a rare absorber with its low preparation cost. In the experiment, CSNPs upconversion optical density by surface plasmon resonance of Au nanoparticle's enhancement can be increased five-time greater than NaYF4 without SiO2 coating. A finite difference time domain simulation and real color luminescence images in this study are also demonstrated.
