Interconnection Optimization for Highly Efficient Perovskite Modules

Abstract: This paper reports on the analysis and comparison of mechanical and laser patterning in the fabrication of perovskite thin-film photovoltaic modules. Besides stability, device upscaling and module fabrication is a key challenge for the commercialization of perovskite photovoltaics. Here, the focus is on the optimization of the P2 interconnection that represents the electrical connection between serially connected cells in a module. The specific contact resistivity for P2 interconnection is determined by using an enhanced transmission line method. Mechanical or laser patterning are used to fabricate 4 cm $^{2}$ modules with aperture area efficiencies of up to 15.3% and geometrical fill factors as high as 94%. With the application of a simulation program with an integrated circuit emphasis-based electrical device model, the interconnection losses are quantified, and optimal designs for perovskite modules are presented.

Electrical resistances of soldered battery cell connections

Abstract: Soldering has a high potential for electrically connecting single battery cells even for multicellular battery assemblies. This work evaluates soldered connections for battery cells by assessing the electrical connection resistance with a special measuring and calculation method. Due to the solder layer in between the joint partners, the current paths differ from welded connections. A resistance network and a finite element model (FEM) simulation are applied to understand these current paths. For the chosen test scenario, simulation predicts a reduction of the total connection resistance by the solder layer. Measured connection resistances and tensile strength are compared to series of measurements with resistance spot welding, ultrasonic welding, laser beam welding and press connections. Not only the connection resistances are lower for soldered brass samples but also the tensile strength is higher. For iron soldering on lithium-ion battery cells, the solder’s liquidus temperature should be below ca. 150 °C. Other heating techniques, such as laser soldering, seem more promising, because the heat input is rapid and extremely localized. As a conclusion, soldering is a good option for connecting battery cells. If the right heating technique is chosen and the parameters are optimally adjusted, soldering could overtrump other connection techniques in some aspects.

Parametric analysis of multilayered unimorph piezoelectric vibration energy harvesters

Abstract: The use of a multilayer piezoelectric cantilever beam for vibration-based energy harvesting applications has been investigated as an effective technique to increase the harvested electrical power. It has been shown that the multilayered energy harvester performance is very sensitive to the number of layers and their electrical connection due to impedance variations. The objective of this work is to suggest a comprehensive mathematical model of multilayered unimorph piezoelectric energy harvester allowing analytical solution for the harvested voltage and electrical power. The model is used to deeply investigate the influence of different parameters on the harvested power. A distributed-parameter model of the harvester using the Euler–Bernoulli beam theory and Hamilton's principle is derived. Gauss's law is used to derive the electrical equations for parallel and series connections. A closed-form solution is proposed based on the Galerkin procedure and the obtained results are validated with a finite elemen...

Research Towards Energy-Efficient Substation Connectors

Abstract: The contact resistance is the main variable that defines the energy efficiency of an electrical connection, its stable performance and long term service. It is worth noting that according to the measurements performed in this work, the contact resistance in substation connectors can be several times that of the connector’s resistance. To reduce connection losses and thus increase connector’s efficiency, it is important to minimize contact resistance, to ensure an efficient connection. The aim of this work is to find out, by means of experimental measurements, the relationship between the different components of contact resistance in substation connectors and the main related variables such as material properties, applied bolts torque, true contact area, or surface’s conditions among others. Furthermore, this study proposes a novel surface treatment for substation connectors, which allows reducing the contact resistance. Experimental measurements demonstrate the effectiveness of the novel chemical treatment in improving energy efficiency in substation connectors.

Linear motion system cable elimination via multiphase capacitive power transfer through sliding journal bearings

Abstract: Electrical loads that slide on moving gantries or rails are common in industry and automation, eg assembly lines, spindle heads, x-y tables, etc These systems often use insulated linear bearings to support mechanical movement during the intended process and a flexible wire-way or cable track provides an electrical connection to power moving parts This paper proposes eliminating the cable connection by using the capacitance of the linear bearings to transfer power between stationary and moving parts, ie the bearings/rails form the coupling of a capacitive power transfer system This is enabled by a 3–5 MHz, 3 phase, resonant inverter capable of driving AC current through the bearing-rail capacitance where it is ultimately rectified on a carriage for final use The high switching frequency enables smaller bearing coupling capacitance to be used with lower developed voltages The inverter uses 650V Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs) in a 3 phase configuration to extend switching frequencies to multi-MHz, thus enabling power transfer levels towards 102-103 watt levels The brushless and wireless excitation of a sliding electrical load, using linear plain bearings sliding on conventional 1 inch diameter anodized shafting serves as a demonstration application Experimental tests at 366 MHz demonstrate 1119W power transfer to a sliding carriage load

Electromagnetic Energy Transmission in Magnetic Pulse Welding of Al/Cu Sheets using 1, 3, 4 and 6 Turn Flat Coils

Abstract: A high pulse current from a capacitor bank is discharged through an insulated flat coil for magnetic Abstract pulse welding of sheets. The sheets (Al/Cu) with a gap are overlapped and fixed on the coil. Electromagnetic coupling exists between the coil and the Al sheet near the coil. This study shows the transmission efficiency of the electromagnetic energy which move from the bank to the coil by using equivalent discharge circuits. The welding is carried out by the energy that moved to the coil. Since the efficiency improves as the equivalent coil inductance increases, the 6 turn flat coil is most effective compared to other coils with fewer turns. The efficiency of the 1, 3, 4 and 6 turn flat coils was calculated based on the welding experiments.

In addition, the charging circuit also includes a first switch; and the two signal pins are switched between a mutual short circuit state and a state of electrical connection with the USB controller by the first switch. According to the charging circuit, because the first switch is arranged between the signal pins and the USB controller and thus the two signal pins are switched between the mutual short circuit state and the state of electrical connection with the USB controller by the first switch, switching of USB interfaces between an SDP type and a DCP type can be realized; and when switching to a DCP type is realized, external charging is realized by using heavy currents, so that the charging speed can increase. Therefore, a technical problem of slow charging speed during external charging of terminal equipment can be solved.
