Fabrication Of Perovskite Absorber For Thin Film Solar Cell Via Sandwich Evaporation Technique
Hui-Hung Shen;Jia-Ci Jhou;Ching-Fuh Lin

Perovskite layer is formed using by two-step sandwich evaporation technique (SET). First, we spin coating MAI and combine PbI2 by thermal evaporation. Second, we evaporate MAI at low-pressure to make better morphology of perovskite crystallize. Through the double-interdiffusion using SET, one can enhance the perovskite solar cells to high PCE=14.6%.

Nickel Silicide Schottky Barrier Diode Infrared Photodetector
Jen-Yao Chang;Zih-Chun Su;Hsin-Han Lai;Ching-Fuh Lin

The silicon-based photodetector is limited by the 1.1 eV energy gap and the cut-off wavelength is about 1.2 μm. In this work, Schottky barrier formed by nickel silicide can effectively extend the cut-off wavelength. Furthermore, the annealing process improves the infrared light signal-noise-ratio (SNR) of the photodetector.

Guan-Yu Lin;Hsueh-Tao Chou;Tien-Ming Wu;Shih-Hung Lin;Zi-Heng Lin

In this study, perovskite solar cells based on three different solvents of PbI2 (DMF, DMSO, and DMF/DMSO with a volume ratio of 7:3) are fabricated by using two-step method. With the improvements of surface morphology and crystallinity of perovskite layer, a decent photoelectric conversion efficiency of 6.02 % is achieved.

Large-size Cation for Slowing Down Ion Migration with Improved Stability of CsPbIBr2
Peter Chao-Yu Chen

CsPbIBr2 is considered as an ideal candidate with proper bandgap. Nevertheless, the working stability hinders its further application. The instability due to ion migration is inhibited by introducing large size cation as shown by PL This approach also leads to improved stability against moisture and light.

Jui-Hsin Tan;Wu-Yih Uen;Wei-Chen Tu

We propose a simple approach to construct flexible rGO photodetectors on paper substrates. The photodetector shows an on off ratio of 1.25 and a responsivity of 18.73 mA/W under 532 nm laser illumination. Our results provide a strategy for fabricating rGO-based photodetectors which show a potential for wearable systems applications.

Surface Passivation on Single-Crystal Perovskite Micro-Plates Improves the Performance of Solar Cells
Tzu-Hsueh Wu;Yung-Fang Yang;Fang-Chung Chen

Perovskite single crystals ideally exhibit better optoelectronic properties than polycrystalline thin films because they possess lower defect densities. Herein, we find that dripping TOPO on the surfaces of perovksite single crystals improve their photovoltaic performance. The power conversion efficiency is averagely improved from 11.9% to 14.76% after the surface passivation.
