Meyer Burger develops a high-efficiency line concept with a silicon heterojunction (HJT) cell based module. This line produces 2400 6-inch busbarless cells per hour and includes cells and modules characterization. The underlying high-efficiency bifacial module technology relies on the Smart Wire Connection Technology (SWCT) and on a Glass-Glass (GG) module design. The SWCT and GG concepts have been...
We propose a design of small-core multiple-layer Bragg waveguide for guiding the THz signal by TE01 mode, which is composed of alternating un-doped silicon (high refractive index) and high-density polyethylene (low refractive index). The group velocity of the THz wave traveling inside this small-core waveguide slows down to below 0.5c, while the propagation loss is less than 0.3 dB per centimeter...
There is great potential in using InGaN as an absorber material in photovoltaic cells, particularly when combined in a heterojunction with p-type Si. However, at typical growth temperatures, Ga and In easily form a eutectic with Si, which creates voids at the interface, resulting in a surface unsuitable for epitaxial growth. In this paper we demonstrate how a simple nitridation process of a Si(111)...
In this paper, the characteristics of the osmium (Os) in textured CoFe/IrMn magnetic film multilayer structure system is investigated and the characteristics of buffer layer and diffusion barrier is also reported. To examine the magnetic behavior, magneto-optical Kerr effect (MOKE) and vibrating sample magnetometer (VSM) are used and XRD is used to examine the crystal structure. As a result, a textured...
This paper describes a low-profile three-dimensional silicon/parylene microelectrode array as basis for practical neural prostheses for use in the central nervous system. The circuit areas of the silicon probes, containing mixed-signal CMOS circuitry for neural stimulation/recording, can be folded over to reduce the overall height of the microassembled array above the cortical surface. The low-profile...
This work describes a low-profile silicon microelectrode array for selectively stimulating in the central nervous system. The array consists of a number of 64-site 8-channel planar CMOS probes, a platform to support the probes on the cortical surface, spacers to hold the probes orthogonal to the platform, and a hybrid chip for platform address decoding. It features integrated circuitry with on-chip...
