摘要: Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as pillars and/or holes, effectively increase the effective absorption length resulting in a greater 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.

摘要: Optoelectronic devices having an improved architecture are disclosed, such as p-i-n hybrid solar cells. These solar cells are characterized by including an insulating mesoporous scaffold in between the hole transportation layer and the photoactive layer, in such a way that the photoactive layer infiltrates the insulating mesoporous scaffold and contacts the hole transportation layer. The infiltration of the photoactive layer in the mesoporous scaffold improves the performance of the hole transportation layer and increases the photovoltaic performance of the solar cell. Solar cells, according to the present invention are manufactured in their entirety below 150° C. and present advantages in terms of cost and ease of manufacture, performance, and energy efficiency, stability over time and reproducibility.

摘要: A transmitter of a wireless power transfer and data communication system comprising a transmitter system including a transmitter housing, one or more high-power laser sources, a laser controller, one or more low-power laser sources, one or more photodiodes, a beam steering system and lens assembly, and a safety system. High-power and low-power beams are directed to corresponding receivers and transceivers of a transceiver system inside a remote receiver system by the controller and the beam steering system and lens assembly. Low-power beams include optical communication to the transceiver system. The photodiodes of the transmitter system receive optical communication from the transceiver system. Low-power beams are co-propagated with and in close proximity to high-power beams substantially along an entire distance between the transmitter housing and the receiver system. The safety system instructs the controller to reduce the high-power sources in response to detected events.
