High Focusing-reflection Subwavelength Gratings with Uni-traveling-carrier Photodetector for High Responsivity

Chen, Qingtao
Subjects: Electronics and Communication Technology >> Optoelectronics and Laser

High focusing-reflection, non-periodic high-contrast grating integrated with a uni-traveling-carrier photodetector (FR-UTC-PD) is proposed to overcome the bandwidth-responsivity trade-off. The responsivity of the FR-UTC-PD is increased by 36.5% while achieving a 3-dB bandwidth of 18 GHz.

High-efficiency photon capturing in ultrathin silicon solar cells with front nanobowl texture and truncated-nanopyramid reflector

Yang, ZH [Yang, Zhenhai][ 1,2,3,4 ]; Li, XF [Li, Xiaofeng][ 1,2,3,4 ]; Wu, SL [Wu, Shaolong][ 1,2,3,4 ]; Gao, PQ [Gao, Pingqi][ 5 ]; Ye, JC [Ye, Jichun][ 5 ]

We present a crystalline siliconthin-film [5 mu m] solar cell decorated by a front nanobowled texture and a rear truncated- nanopyramid silver reflector. This design substantially suppresses the overall light reflection and enhances the optical resonances
