  • Patent number: 10236689
    Abstract: A solar cell management system for increasing the efficiency and power output of a solar cell and methods for making and using the same. The management system provides an electric field across one or more solar cells. The imposed electric field exerts a force on both the electrons and holes created by light incident on the solar cell and accelerates the electron-hole pairs towards the electrodes of the solar cell. The solar cell management system considers variations in configuration of solar cells to maximize the power output of the solar cells. The accelerated electron-hole pairs have a lower likelihood of recombining within the cells' semiconductor's material. This reduction in the electron-hole recombination rate results in an overall increase in the solar cells' efficiency and greater power output.

  • Patent number: 10193345
    Abstract: A solar cell management system for increasing the efficiency and power output of a solar cell and methods for making and using the same. The management system provides an electric field across an individual solar cell, an array of solar cells configured as a panel, or a group of solar panels. The imposed electric field exerts a force on both the electrons and holes created by light incident on the solar cell and accelerates the electron-hole pairs towards the electrodes of the solar cell. Compared to conventional solar cells, these accelerated electron-hole pairs travel a shorter distance from creation (by incident optical radiation) and spend less time within the solar cell material, therefore the electron-hole pairs have a lower likelihood of recombining within the cells' semiconductor's material. This reduction in the electron-hole recombination rate results in an overall increase in the solar cells' efficiency and greater power output.

Hydrogen increases the laminar flame speed of the jet fuel during combustion thus causing more fuel to be burned and lowering particulate matter emissions. Hydrogen is supplied to the jet engine at levels well below its lower flammability limit in air of 4%. Hydrogen and oxygen is produced by an electrolyzer from nonelectrolyte water in a nonelectrolyte water tank. The system utilizes an onboard diagnostic (OBD) interface in communication with the jet's control systems, to regulate power to the system so that hydrogen production for the jet engine only occurs when the jet engine is running. The hydrogen gas produced is immediately consumed by the jet engine. No hydrogen is stored on, in or around the jet.

  • Patent number: 9029684
    Abstract: The present disclosure relates to a hybrid solar receiver that generates electricity and heat simultaneously. The solar receiver comprises photovoltaic cells for converting concentrated light on the cells into electricity. The receiver also includes a heat pipe having a heat discharge area that serves as an evaporator for discharging heat accumulated on the photovoltaic cells to a dissipation area. A dual-function interface layer is positioned between the photovoltaic cells and the heat pipe. The interface layer electrically insulates the photovoltaic cells from the heat pipe and instantaneously transfer the heat accumulated on photovoltaic cells to liquid coolant in the heat pipe. A surface of the photovoltaic cells is coated with an encapsulation layer. A transparent plate is deposited on the encapsulation layer.

  • Publication number: 20150122309
    Abstract: The invention relates to a solar energy collection system that uses linear parabolic concentrators designed on a small scale and with a modular configuration that allows optimum usage of solar collection surface area in places such as the roofs or flat roofs of factories or shops where space is generally small or irregular. The solar collector is coupled in rows actuated by a fully autonomous system for electronically controlling solar tracking, the operation of which is based on an algorithm programmed in a microcontroller. An autonomous solar tracking system can efficiently control two parallel rows with a pre-defined number of solar concentrators, as well as automatically detecting the presence of impurities on a reflecting radiation surface for the maintenance thereof. The thermal energy produced is harnessed by a heat exchanger, the operation of which is based on conduction, convection and radiation for dehydration uses.

  • Publication number: 20150083195
    Abstract: The invention concerns a device for collecting infrared solar radiation by heating a circulating blade of air circulating between two transparent glazed walls. The first glazed wall polarises light in a circular manner. The second glazed wall reflects infrared radiation towards the first glazed wall. The infrared radiation which has been reflected has changed polarisation direction and is then absorbed by the first glazed wall which heats up, and in turn heats the circulating blade of air in contact with same.

  • Publication number: 20150083196
    Abstract: Provided is a magneto-thermoelectric generator (MTG) device for energy harvesting and more particularly a device for converting waste thermal heat from a photovoltaic cell into mechanical energy and ultimately into electrical energy. Embodiments operate on the principle of thermally-induced switching between open and closed states of a ferromagnetic switch to generate mechanical oscillations that cause strain in a piezoelectric material, resulting in the generation of electrical energy. A structure capable of providing a non-linear restoring force provides mechanical energy to the device, which is a significant improvement over prior art MTG devices employing a linear spring restorative force. The device is also provided as a hybrid photovoltaic (PV)/MTG energy harvester for scavenging heat from photovoltaic cells. The hybrid PV/MTG device is particularly useful for harvesting waste heat to boost power generation, extend flight duration, and provide thermal management aboard HALE platforms.

  • Patent number: 8921683
    Abstract: A solar powered generator (100) has thermoelectric elements adjacent to and below solar cells. Concentrated sunlight is provided. A heat sink (104), which can be variable in temperature or efficiency, is in contact with the cold junction (108) of the thermoelectric device (103). The thermal resistivity is designed in relation to the energy flux, whereby the thermoelectric device (103) develops a gradient of several hundred Kelvin. Preferably the solar cell comprises a high band gap energy semi-conductor. The generator (100) maintains relatively consistent efficiency over a range of cold junction (108) temperatures. The heat sink (104) can be a hot water system. High efficiencies are achieved using nanocomposite thermoelectric materials. Evenly but thinly dispersing the thermoelectric segments in a matrix of highly insulating material reduces the amount of material required for the segments without sacrificing performance.
