Ngo, Thi Thuy,Yazdi, Jafar,Mousavi, S. Jamshid,Kim, Joong Hoon American Society of Civil Engineers 2016 Journal of hydrologic engineering Vol.21 No.12
<P>In the context of urbanization and waterworks construction, detention basins located in upstream tributaries have become one of the most-effective technical solutions for downstream flood reduction. This technical note proposes a new optimal approach for determining the most-effective design combination of detention basins (in terms of their sizes and locations) in a watershed utilizing linear reservoir theory. The optimal detention basin is obtained by minimizing the deviation of downstream peak discharge from river capacity discharge. With the presence of a detention basin in an upstream river, the flood peak downstream decreases by 33%, corresponding to two scenarios of rainfall duration with a return period T=100 years. The storage volume estimation of the optimal detention reservoir proposed in the present paper demonstrates the high applicability of this optimization approach.

<P>In this study, a recorded high open-circuit voltage (V<SUB>oc</SUB>) of 1.61 V and fill factor (FF) of 76.65% of a-Si:H p-i-n/heterojunction with intrinsic thin layer (HIT)-type multi-junction solar cells were achieved using grain size enlargement within the p-type <I>μ</I>c-Si:H layer in a p-type <I>μ</I>c-Si:H/n-type a-Si:H tunneling recombination junction (TRJ) layer. The p-type <I>μ</I>c-Si:H layer’s conductivity increased from 1.74?×?10<SUP>−4</SUP> to 0.1 S cm<SUP>−1</SUP> as the film’s crystallinity increased from 41.5% to 67.5%. The a-Si:H p-i-n/HIT-type multi-junction solar cells also benefited from the tuning up crystalline p-type <I>μ</I>c-Si:H layer, showing the increase of V<SUB>oc</SUB> and FF from 1.5 V and 49.88% to 1.61 V and 76.65%, respectively; while the short-circuit current density (9.38?±?0.2 mA cm<SUP>−2</SUP>) did not change significantly. These are the highest V<SUB>oc</SUB> and FF values achieved in a-Si:H p-i-n/HIT-type multi-junction solar cells, recently. From dark current-voltage analysis, it was deduced that the enhanced crystalline films could assist in suppressing carrier interference in the TRJ layer, thus reduces electric field distortion and mitigates recombination in the device. In summary, an enhanced crystalline p-type <I>μ</I>c-Si:H layer could be a viable option for ensuring an excellent TRJ layer, thus achieved high efficiency of inorganic/c-Si tandem solar cells. Using optimal condition with crystallinity of 74.1%, the photovoltaic parameters of the device yield V<SUB>oc</SUB>, J<SUB>sc</SUB> and FF of 1.51 V, 13.01 mA cm<SUP>−2</SUP> and 71.45%, which in turned giving an efficiency of 14.04% for a-SiGe:H p-i-n/HIT-type tandem solar cell.</P>
