    Investigation on the role of Sb doping on grain growth and properties of solution-processed CuIn(S,Se)2 by Ho, John Chun Wan

    Published 2015
    “…The enhanced lifetimes can be attributed to defect related recombination from less grain boundaries and the higher density of secondary (204)/(220) grain orientations which has lower density of non-radiative recombination centers. Conductive AFM mapping on Sb doped device with best device performance shows similar current map under positive bias and minimal current when the tip bias is negative, illustrating minimal leakage current in the device. …”

    Development of selenization/sulfurization-free CuIn(S,Se)2 for thin film solar cells applications by Wang, Mengxi

    Published 2015
    “…As mentioned earlier, large CIGS grains will result in films that showed better solar cell performance and one of the reasons is that they have fewer defect sites and recombination centers. As a route to larger grain size, nanoparticles is first synthesized and by encouraging growth in these individual CIGS nanoparticles, micron sized grains can be achieved. …”

    A new method to estimate slab dip direction using receiver functions and its application in revealing slab geometry and a diffuse plate boundary beneath Sumatra by Feng, Mingye, Chen, Ling, Wei, Shengji, Wang, Xin, Wang, Xu, Wu, Zimu

    Published 2023
    “…The thicker LVL with a non-negligible difference in the dip directions of its upper and lower bounds in the center of Sumatra is interpreted as a partially serpentinized mantle layer above the oceanic crust, forming a distinct channel atop the subducting slab. …”
