Systems and methods for wiring solar panel arrays
A solar power system may include a combiner module, one or more rows of solar panels connected to the combiner module, and one or more wiring circuits connecting the one or more rows of solar panels to the combiner module. Each circuit may include an inter-module wiring arrangement that connects individual solar panels to each other in series, and a return wiring arrangement that connects the inter-module wiring arrangement to the combiner module. Each inter-module wiring arrangement may be arranged such that at least some solar panels are wired to other solar panels in the same row in a substantially alternating manner, such that non-adjacent solar panels in the same row are wired directly in series to each other. This arrangement may reduce the total length of harness wires needed to connect the one or more panel rows to the combiner box, as compared with conventional wiring schemes.
Photodetector with surface plasmon resonance
Methods and structures for providing single-color or multi-color photo-detectors leveraging plasmon resonance for performance benefits. In one example, a radiation detector includes a semiconductor absorber layer having a first electrical conductivity type and an energy bandgap responsive to radiation in a first spectral region, a semiconductor collector layer coupled to the absorber layer and having a second electrical conductivity type, and a plasmonic resonator coupled to the collector layer and having a periodic structure including a plurality of features arranged in a regularly repeating pattern.
Process of fabrication of electronic devices and electronic device with a double encapsulation ring
An integrated circuit chip is mounted on top of a base wafer, and a protection wafer is mounted on top of the integrated circuit chip. An encapsulation block is formed around the integrated circuit chip and the protection wafer and on a peripheral part of the front face of the base wafer. The encapsulation block includes a first encapsulation ring arranged around the integrated circuit chip and the protection wafer, having an annular beading protruding with respect to the front face of the protection wafer and forming a peripheral groove (24) recessed with respect to this protruding annular beading. A second encapsulation ring of the encapsulation block fills the peripheral groove of the first encapsulation ring.
