Design and Analysis of Triple-Layer Antireflection Film for Crystalline Silicon Heterogeneous Solar Cell
Shi Kaiying, Han Shaowen, Lin Bencai, and Sun Xilian
ITO film, as typical antireflection film in crystalline silicon heterogeneous solar cells, has low UV transmittance and high near-infrared optical loss, which restricts the efficiency improvement of the solar cells. Therefore, triple-layer antireflection film was designed in this paper. Firstly, we simulated and analyz

Multiple-Scattering Approximation Model Among Horizontally Adjacent Fields for Three-Dimensional Radiative Transfer in Cloud Remote Sensing
Zhang Yin, Yan Hao, Ma Jun, Yan Junhua, Zhi Xiyang, and Gong Jinnan
An approximation model of multiple-scattering among horizontally adjacent fields is proposed as a means of improving the three-dimensional (3D) radiative transfer calculation for clouds in remote-sensing applications. Horizontal radiative-exchange equations are established after analyzing the mechanism of radiation flu

Michelson Interferometric Humidity Sensor Based on Photonic Crystal Fiber
Shao Min, Sun Haonan, Zhang Rong, Liu Yinggang, and Qiao Xueguang
A fiber-optic Michelson interferometer based on a photonic crystal fiber (PCF) is proposed, constructed by fusing a piece of PCF and a single-mode fiber (SMF). The taper between the SMF and the PCF works as a coupler. It excites the high-order cladding modes and couples the fundamental mode of the core and high-order c

Measurement-Device-Independent Quantum Key Distribution of Finite Detector's Dead Time in Heralded Pair Coherent State
He Yefeng, Zhao Yankun, Li Chunyu, and Guo Jiarui
In its practical applications, quantum key distribution is affected by the finite detector dead time. When the signal pulse transmission rate is too large, the probability of detector's measurement failure increases and the security key generation rate decreases. In this paper, the finite detector dead time problem
