The present invention relates to methods, tools and systems for manufacturing a durable and portable power-conditioned personal solar system charging apparatus. Various voltage and amperage matching algorithms are manipulated to particularize the personal solar system to power and/or charge an intended portable device or a set of intended portable devices having direct current (DC) load requirements. The optimized personal solar system that is matched to an intended device allows direct coupling to the intended device without the use of an internal battery or ancillary electronic circuit boards to distract the personal solar system output, and facilitates fast charging modes.

A mid-infrared tunable metamaterial comprises an array of resonators on a semiconductor substrate having a large dependence of dielectric function on carrier concentration and a semiconductor plasma resonance that lies below the operating range, such as indium antimonide. Voltage biasing of the substrate generates a resonance shift in the metamaterial response that is tunable over a broad operating range. The mid-infrared tunable metamaterials have the potential to become the building blocks of chip based active optical devices in mid-infrared ranges, which can be used for many applications, such as thermal imaging, remote sensing, and environmental monitoring.

Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as holes, effectively increase the absorption of the photons. Using microstructures for absorption enhancement for silicon photodiodes and silicon avalanche photodiodes can result in bandwidths in excess of 10 Gb/s at photons with wavelengths of 850 nm, and with quantum efficiencies of approximately 90% or more. Their thickness dimensions allow them to be conveniently integrated on the same Si chip with CMOS, BiCMOS, and other electronics, with resulting packaging benefits and reduced capacitance and thus higher speeds.

An optoelectronic device for detecting electromagnetic radiation includes a body of semiconductor material. A first region and a second region that form a junction are provided within the body. A recess extends into the body and is delimited by side arranged transverse to a main surface of the body. The junction is exposed by the sidewall to coupled electromagnetic radiation received in the recess into a photodiode formed by the junction.

A barrier film layer, a photoelectric device comprising the barrier film layer and a manufacturing method of the photoelectric device are provided. A material forming the barrier film layer includes a topological insulator, and the barrier film layer is formed on a surface of an base plate which is patterned. In this way, a better package of the photoelectric device can be achieved.

A photodetector includes an anode that is transparent or partially transparent to light, a cathode and an active layer disposed between the anode and the cathode. The active layer includes a nanocomposite material that has a polymer blended with nanoparticles or organic electron trapping particles. The photodetector has a low dark current when not illuminated by light and has a high conductivity when illuminated by light, in which the light passes the anode and is absorbed by the active layer.

The present invention is directed to an apparatus for stacking a plurality of solar module arrays each having a plurality of solar panels. The apparatus includes a lower portion disposed on top of a first solar panel support channel corresponding to a first solar module array, and an upper portion for supporting a second solar panel support channel corresponding to a second solar module array, wherein the second solar module array is stacked above the first solar module array.

The disclosure describes various stackable corner protector configurations. The corner protectors can have curved lateral surfaces that allow the corner protectors to be decoupled from a photovoltaic module to which they are coupled to by rotating one end of the corner protectors away from the object. This removal process works even more efficiently with multiple stacked corner protectors as the stacked corner protectors can be concurrently removed from the object by rotating the stacked corner protectors away from the object together. The corner protector can also include one or more attachment features for securing the corner protector to the object. For example, when the corner protector is installed on a photovoltaic module, the attachment feature can engage a lip defined by a recess or channel of the photovoltaic module.
