Effect of Ultrasonic Bonding Parameters on the Contact Resistance and Bondability Performances of CIGS Thin Film Photovoltaic Solar Panel
No full textThis article aims to investigate the optimal ultrasonic bonding parameter namely bonding pressure, bonding energy, and bonding amplitude that can minimize the contact resistance (R-c), maximize the peel strength, and identify the possible failure modes of ultrasonic Al bond on Mo back contact layer of copper indium gallium (de)selenide (CIGS) thin-film photovoltaic (TFPV) solar panel. The transmission line method was used to measure R-c and a peel test was carried out to measure the peel strength and the possible failure modes of ultrasonic Al bond on the Mo layer. Design of experiment using D-optimal method was utilized to evaluate the effect of the ultrasonic bonding parameter toward the R-c and peel strength of the Al bond on the Mo layer. Individual and combination of the ultrasonic bonding parameter have a significant effect on the quality of Al bonds on Mo back contact layer of CIGS TFPV solar panel. Possible failure modes could be identified through the application of the higher value of individual ultrasonic bonding parameter while keeping constant other bonding parameters and through the qualitative result of the load-displacement profile obtained from the peel test. However, sample 2 with bonding pressure of 3 bar, bonding energy of 20 Ws, and bonding amplitude of 7.7 mu m is the best-optimized bonding parameter window that can be applied to obtain ultrasonic Al bond with lower R-c and higher peel strength. It was noted that bonding pressure is the most sensitive bonding parameter followed by bonding amplitude and bonding energy.This work was supported in part by the Ministry of Higher Education of Malaysia under the Fundamental Research Grant FRGS/1/2020/TKO/UNIKL/02/10 and in part by the Universiti Kuala Lumpur under Short Term Research under Grant str19087.Zulkifli, MN (corresponding author), Univ Kuala Lumpur, British Malaysian Inst, Elect Engn Sect, Gombak 53100, Malaysia.

Zulkifli Nasution, MSc, PhD (Chair); Dr. Ir. Rahmanta, M.Si (Member), Kasyful Mahalli, SE, M.Si (Member). This research was conducted to identify the general condition of flooding problems in the city of Medan and its causes as well as flood prevention needs based on these general conditions. Therefore, prevention solutions created flooding problems with the construction of flood channels with the assumption that the existence of the flood canal flooding problems originating from the deli river water, rain water and urban drainage water can be accommodated in buildings that flood channel. And flooding that always occurred in Medan can be minimized gradually. Research conducted at the location of points where the floodwaters carried out a study of general conditions just as the causes of the floods and required. Therefore, a study conducted specifically on the canal flooding that has reached the 3.8 km long. Where the upstream channel is located on River Flood Deli and while located on the lower Percut River and in any area of Medan with the several districts, namely : Medan Johor distric, Delitua district and Marendal district. With the construction of flood canals in the city of Medan, which is urban flood management system is part of an integrated planning and regional development, with seeing the flood based on hydrological boundaries, and administrative boundaries and synergy between hydrological boundaries with administrative boundaries will further enhance the development of quality of life and public life in Flood and around the canal spur economic growth for the locations and places for public housing is often affected by flooding.Jones Hendra M.

A study on the acoustical absorption behavior of coir fiber using miki model
No full textSound absorption capacity of natural coir fiber collected from coconut husk has been explored and predicted using Miki's empirical model. Experiments are conducted in impedance tube to validate the analytical outcomes for three samples having different thickness backed with and without air gap. Results show that the empirical model can estimate the absorption coefficient of coir fiber favourably well and shows higher accuracy than the Delany-Bazley model. Discrepancies between the predicted and measured absorption coefficient is very low although some inevitable irregularities is observed in the peak positions. However, presented Miki model can evaluate the overall acoustic behavior of coir fiber. This approach can be considered as a very simple and preliminary analytical solution for coir fiber acoustical characterization without considering several physical parameters of porous media. In addition, as a result, no complicated measuring procedure has to be followed to initiate the preliminary study for this material.M. Ayub, R. Zulkifli, M. H. Fouladi, N. Amin, M. J M No
