Ponmudi Selvan T;Chien-Chih Lai;Tsung-Chun Huang;Chih-Hung Tsai

In this study, NiOx thin film was prepared by the solution-combustion process at 250 °C, a temperature lower than the actual reaction temperature. The maximum power conversion efficiency of inverted perovskite solar cells made with pristine NiOx and 5% Zn-NiOx as the HTL was 13.62% and 14.87%, respectively.

Chen-Fu Lin Synthesis and Material characteristics of Multi-dimensional Pseudohalide perovskite by Low pressure Vapor-Assisted Solution Process
Chen-Fu Lin;Peter Chen

In this study, the pseudohalide perovskite in 2D/3D hybrid perovskite films were made by the low-pressure vapor-assisted solution process (LP-VASP). Using the excessive PEAI doped in the precursor, and the halogen replaced I ions replaced with SCN ions. It was found that SCN ions can inhibit the appetite growth of 3D perovskite and existed in the bottom of perovskite film.

Hai-Xing Chang Study on Different Doping Ratio of The Cesium Chloride and Formamidinium Iodide on Perovskite Solar Cell
Hai-Xing Chang;Wei-Chen Lin;Ching-Ho Tien;Lung-Chien Chen

We devise a different doping ratio of the cesium chloride and formamidinium iodide on FAPbI3. Cesium (Cs) can stabilize the α phase of perovskite. Consequently, the best power conversion efficiency of perovskite solar cells has increased from 14.6% to 18.9%.

Chien-Hsing Chen;Chang-Yue Chiang;Yang Lu;Cheng-Ling Lee

This study used an femtosecond laser machining system developed two types of fiber-optic interferometers with a sensing function. The refractive index sensor sensitivity of the fiber-optic Mach-Zehnder interferometer was 35.1nm/RIU. The fiber-optic Fabry-Perot interferometer of two microholes only take 0.005 s that is much faster than that by one microhole on the hollow code fiber, and has the potential capability for on-site, in-vivo, and remote sensing, and has the potential use for disposable sensors.

Bo-Rong Jheng Utilization of Nanoporous NiOx Layer and NiOx Thin Film as the HTL in Perovskite Solar Cells for Comparison
Zhang-Wei Huang;Bo-Rong Jheng;Chih-Yu Chang;You-Wei Wu;Sheng-Hsiung Yang

The nanoporous nickel oxide (NiOx) layer as well as NiOx thin film was prepared via chemical bath deposition as the hole transport layer (HTL) in inverted perovskite solar cells (PSCs). The sponge-like structure of the nanoporous NiOx helps to grow pinhole-free perovskite film with larger grain size compare to the NiOx thin film. The inverted PSCs based on the nanoporous NiOx layer showed the highest efficiency of 13.43% and negligible hysteresis that was better than the one using the NiOx thin film as the HTL. Moreover, the PSCs sustained 80% of their initial efficiency after 50 days storage.

Zheng-Yue Jian Study of Metal Doped Nickel Oxide Nanoparticles as Hole Transporting Layer for perovskite solar cells
Zheng-Yue Jian;Zheng-Yue Jian

Perovskite solar cells (PSCs) with inverted structure generally present higher stability and negligible hysteresis effect. One of the most important parts of the inverted photovoltaic is the hole transporting layer (HTL). In this study, we choose metal doped NiOx as HTL material and synthesized it by nanoparticles method, which does not need anneal process. Moreover, NiOx nanoparticles does not react with perovskite layer and the energy level alignment of NiOx thin film is more favorable with active-layer. In this report, NiOx based PSCs with optimized metal doping ratio has reached 14.33% conversion efficiency as compared to 12.59% without metal doping.

Peter Chen Visualization of the Ion Migration: Probe & Set Operation
Peter Chen

All inorganic perovskite has developed as a candidate for photovoltaic application due to its decent thermal stability. Nevertheless, the ion migration remains an issue due to the instability of mixed halide perovskite under illumination with the presence of phase segregation. Here we present a technique to investigate the light-induced ion migration within the CsPbIBr2: Probe and Set operation. By tuning the power and the duration of the laser illumination, we visualize the phase segregation and its reversal via photoluminescence measurement.

YuTang Lin;KuoPing Chen;MinWen Yu

Tungsten disulfide (WS2) and graphene are two-dimensional (2D) materials of typical features. They process the ability to modulate and communicate signals between electronics and photonics in an extreme lateral dimension. However, the characteristics of primitive graphene photodetector has weak photo responsivity. In this research, via the WS-2/graphene heterostructures to induce more electrons by internal electric fields and achieve the high photoresponsivity (~5.7A/W). Finally, the correlation between photoluminescence (PL) and photocurrent is analyzed.
