Jue Wang Hafnia and Silica Based Short-Wave-Pass Filters for the DUV
Jue Wang, Corning Advanced Optics (USA); Joseph M Kunick, Corning Inc. (USA)

DUV short-wave-pass filters derived from reactive plasma ion assisted deposition of HfO2/SiO2 suppress solar background at wavelengths above 300 nm and maintain high DUV transmission between 260-290 nm. We obtained a transmittance of 93% in the DUV with blocking greater than 6 OD in the longer UV wavelengths. Surface morphology analysis and scatter estimation indicate that it is possible to enhance and extend the blocking region from the UV to VIS and even IR while still maintaining high transmittance in the DUV solar noise-free band.

Ting-Yen Lin An ultrathin optical cavity with a metasurface as one of the reflectors
Yi-Jun Jen, Ting-Yen Lin, National Taipei University of Technology (Taiwan)

In this work, a metasurface comprises subwavelength polymer grating with obliquely coating of silver is adopted as one reflection mirror in Fabry-Pérot cavity. The polarization dependent transmittance peaks are derived and compared with the traditional Fabry-Pérot cavity. It is found that the cavity with metasurface mirror is thinner than the traditional cavity because the reflection phase of the metasurface is different from that of a silver film.

Hsin-Ting Lin Thermal Annealing Effect on Harvesting Infrared Solar Energy Using Hot Carriers in Metal-Silicon Junction Solar Cells
Hsin-Ting Lin, Chung-Han Chang, Ching-Fuh Lin, National Taiwan University (Taiwan)

We explored metal-silicon junction solar cells to absorb Infrared regime above 1100
nm using hot-carrier effect. The photovoltaic conversion efficiency of the solar cell can be
optimized via thermal annealing process. Besides, we analyzed the morphology of metal films
under different annealing temperatures via X-ray diffraction (XRD) and scanning electron
microscopy (SEM). The hot-carrier solar cells are achieved with a record efficiency of above

Yu-You Su Optical properties of a-Six:H/a-Siy:H superlattices
Yeu-Long Jiang, Shuo-Heng Chien, Yu-You Su, National Chung Hsing University (Taiwan)

Pulse-wave modulation plasma with change the RF power was used to fabricate and control the structural and optical properties of hydrogenated amorphous a-Six:H/a-Siy:H superlattices films. The optical characteristics of single a-Six:H (barrier layer), a-Siy:H (well layer) and a-Six:H/a-Siy:H superlattices were investigated.
