    Design of a Highly Efficient Subwavelength Antireflective Structure for Solar Cells by Lin Chen, Zhao Huang

    Published 2022-01-01
    “…Our simulations show that the weighted average reflectance of the subwavelength AR structure is as low as 4.2% in the 400–1100 nm spectral range in the normal incidence condition and almost 10-fold reduction compared with a bare silicon surface. When placed on the front side of a simple Si thin-film photovoltaic solar cell, this subwavelength AR structure leads to an improved light absorption with simulated results showing an increase of 53% short-circuit current compared to a flat solar cell. …”

    An Evaluation Model for Tailings Storage Facilities Using Improved Neural Networks and Fuzzy Mathematics by Sen Tian, Jianhong Chen

    Published 2014-01-01
    “…The varying proportions of cross validation were calculated, demonstrating that this method has better evaluation performance with higher learning efficiency and faster convergence speed and avoids the oscillation in the training process in traditional BP neural network method and other primary neural network methods. The entire analysis shows the combination of the two methods increases the accuracy and reliability of the safety evaluation, and it can be well applied in the TSF safety evaluation.…”

    Evolution and Influencing Factors of Township Spatial Form: A Two-Dimensional Perspective by Yanpeng Gao, Wenjun Chen

    Published 2020-01-01
    “…From 2009‒2019, the integration level of the subdistrict improved and the scale and number of integration axis increased, forming a multicore tree-shaped structure. Pearson’s correlation analysis showed that urbanization is the main factor affecting the spatial and temporal land-use evolution, with transportation convenience, industrial park, and proximity to the river having little effects. …”
